How to Choose Baby Food Storage Containers: Real Tips from Working Moms

"We just want them to eat well and grow up healthy."
That simple wish lies at the heart of every parent.

This is especially true during the weaning stage, when babies vary greatly in how much and how quickly they eat. Parents often find themselves unsure of how much food to prepare, disappointed when their carefully made meals go uneaten, or confused about the best way to store leftovers. It’s a time of constant trial and error.

So how can parents navigate the daily challenge of preparing baby food, especially when time is limited?

In this edition of "Crossroads to the Future," members of the accounting team at Seven-Eleven Japan’s Osaka Office and researchers from Akachan Honpo’s "Life with Babies Lab" gathered for a roundtable discussion on the topic of baby food storage containers.

To start, could you all share what kind of storage containers you’re using? Feel free to mention any you used in the past as well. I’d also love to hear why you chose them.

When I started baby food, I gathered information from YouTube and Instagram, and that’s where I found the block tray from a particular brand. I’ve been using it ever since. My older child is now 2 years and 8 months old, but I still use the tray to store homemade jelly.

I use the same one too. First, I checked out the product lineup in-store, then looked up more information on Instagram. I saw so many photos of it there that I thought, "This must be a good choice," and decided to give it a try.

My sister recommended using trays, saying, "It makes things so much easier," so I started using portioned trays. But the first one I tried was really stiff... It was hard to use every time, so I ended up getting about three softer ones in different sizes.

I think I also used portioned trays from the very beginning. I’d make a fairly large batch all at once and line them up in a row.

I started with trays too, but when the baby food was still very runny and in small portions, I switched to using freezer bags. I’d mark out single portions with chopsticks, and when it was time to use them, I could just snap off a section and heat it up. It was really convenient!

Easier Storage, Easier Meal Prep

Whether it’s advice from people close to you or tips from social media, there are many ways to choose. But in the end, what really matters is how it actually works for you. While using the containers, were there any moments where things didn’t go as planned or left you feeling unsure?

With block trays, if you put things like meat sauce or anything tomato-based in them, they tend to get stained. Sometimes no matter how much I wash them, the color doesn’t come out, and I’d find myself wishing they were easier to clean.

Also, don’t the lids tend to shift quite a bit? Containers with attached lids stay closed firmly, but with block trays, the contents expand when frozen, and the lid ends up getting pushed out of place.

I totally get that! I think containers that give that "click" when the lid closes are much easier to use. Also, depending on the type, some lids are really stiff, and I’d have trouble getting the frozen baby food out without using a lot of force. I know you can let it thaw a little first, but when I was in a hurry, I’d ask my husband to help get it out.

Also, with block trays, even if I only want to freeze a small amount, I still have to put the whole tray into the freezer. I kept thinking, "This takes up so much space." I’d love it if there were smaller-sized options.

Nakabou

Nakabou

I’ve felt the same way! Also, with the tray I use, each block is the same size. But with baby food, the portions vary—like 50 grams for porridge and 20 grams for vegetables. So I end up having to take out 3 or 4 blocks just for one meal.

Thank you all for your input. That said, having baby food prepped and stored really does make a big difference—it’s tough to start from scratch every time. Since you’re all working moms, do you have any tips or tricks for managing baby food prep while balancing work and parenting?

Yokoyama

I usually made about five days to a week’s worth of food over the weekend. I’d store everything in block trays and just heat it up when it was time to feed—keeping it that simple made things so much easier. I also used to mash bananas into a paste and store them in freezer bags.

I just returned to work from maternity leave, so I don’t have time to make baby food during the week. That’s why I prepare a whole week’s worth on either Saturday or Sunday. I use a pressure cooker to cook a big batch of vegetables, then I chop them up or change the seasoning before portioning them into storage containers.

It’s really inspiring to hear how you’re all finding ways to manage, even with your busy schedules. I’m learning a lot from your experiences.

Small Changes That Could Improve Parenting

So far, we’ve heard about how each of you approaches baby food prep and storage in your own way. If you don’t mind, I’d love to hear your thoughts on what lies a little further ahead—like your hopes for how companies or society might change to better support parenting in the future. Is there anything you wish could be different?

These days, with social media, we have access to so much information—but that also means we’re exposed to a lot of harsh opinions about parenting. Seeing those can make you feel like you have to do things a certain way. I just wish society could be a little more accepting of different parenting styles—a place where we can raise our kids more freely and without so much pressure.

Kamiji

I share parenting responsibilities with my husband, but because of his role at work and the nature of his job, I still end up handling most of it. I feel that active involvement by fathers in childcare hasn’t fully taken root yet, so I really hope we move toward a society where that kind of mindset is more naturally accepted.

Kurihara

That’s so true—there are aspects of parenting you just can’t handle alone. That’s why I really appreciate that our company created this kind of space for us today.

I often chat with friends about how things could be better, but we rarely get the chance to voice those thoughts in a product development setting. If our opinions can help support other moms who are doing their best, that would make me really happy.

Working at Akachan Honpo can sometimes create the assumption that everyone has a solid understanding of childcare. But today offered a valuable opportunity to hear real, everyday experiences from different perspectives. A heartfelt thank you to everyone who joined.

Weaning is a daily practice that supports a baby’s growth. In the midst of busy days, how do parents approach it, and what little tricks do they use? This conversation brought out those real, lived experiences.

Even small struggles or simple ideas, when voiced, might be helpful to someone else. It was a time that reminded us of that very possibility.
