When the babies go for their 6 month checkup next week, they will surely have outgrown their infant carriers. Abby outgrew hers at 4 months, so she was nowhere near sitting up unsupported in grocery carts. I solved my problem by buying a Buggy Bagg (HIGHLY recommend them if you have a singleton!), which was great because it was well-padded and came with a detachable pillow. That pillow was what sold me on the Buggy Bagg and was perfect for helping her sit up in the carts.
Now, we're in a similar situation with the babies. They are very close to sitting up unsupported, but they're not quite there yet. Since I won't have the infant carriers to load up one cart at Target any more, I have 3 options.
1. Use the Buggy Bagg in a single cart for one baby & sling the other while Abby walks next to me. The only problem is that we don't use the sling very often, so they're not used to it. Until they're comfortable in it, we'll have to keep these trips short.
2. Push the babies in the double stroller while pull a cart. Not only has it been a big pain when I have to shop by myself and have to use 2 grocery carts, but taking the stroller would limit space in the minivan. We've had to get creative when we forget to take the stroller out before going to the grocery store.
3. Do the bulk of my shopping at the grocery store with the race car up front and room for the babies in the back. Since they're not quite sitting unsupported yet, they'll need some padding to help them. I was hoping Buggy Bagg would make a double cart cover thing with pillows, but no such luck. I have found several cute ones that say they can be used in the big double carts, but they don't come with pillows so they don't really help me. Plus, they only have 2 leg holes, so each baby sits inside one leg hole and has no fabric or padding between their legs. This isn't a dealbreaker for me, but I haven't found one that comes with a pillow. Honestly, I do love some of the patterns I've found, particularly the Itzy Ritzy ones, but how would I support them into a sitting position? Is it padded enough to help? The Buggy Bagg wasn't. They are very close to sitting on their own, so it would really only be for 2 or 3 weeks, tops.
I'd love to hear any suggestions or experiences you may have with grocery cart covers. Thanks!
