I bought these bowls because they're just so cute and cheap (I got them for 3.99). Im one person who likes compact little things so if you're like me you'll love them too. They're good for day trips without having to bring around big bowls that would take up space in your diaper bag, or when taking baby to grandma's or the babysitter. They fit nicely in my small cooler without the bulk. I was able to put about 10 tablespoons of dry cereal and about 2-3 oz of mashed baby food, which might not be enough for an older baby but ok for me coz my baby is only 7 mos old and that's about how much he eats. I havent tried putting them in the bag yet to see if the covers will stay put but they are pretty tight so hopefully the food doesn't spill. Just to be on the safe side, I'd put them in ziplock bags if the're going to be in the same bag as other items like baby's clothes. I gave it four stars for the fact that they're small and they might not be suitable for others and that these bowls are best used if your baby is just starting on solid foods up until, well, they start eating more. Then you'll have to switch to bigger bowls.
Updates:
I've been using these bowls for about a month now and Id say they're great. Id fill them with oat rings, dry cereals and mashed fruit and toss them in my bag and so far the covers have stayed put and havent had any spills. I also find the spoon very convenient and easy to use. I now prefer using it because the part the goes in the mouth is deep enough and the handle is long. I just love the spoon so much that I wish they'd sell it separately too.
Now that my son is older and eats more I'd fill them to the brim and we're good for the entire day when we're out. I would probably get one more since I lost one while we were out swimming but is ok coz they're not really that expensive.
