My son is 6 months old but still only a supported sitter.... he's tall and skinny so he doesn't have a belly to lean on either lol. I just wanted to know when you put your baby in the seat of a cart? We're they supported sitters or sitting up on their own? I have one of those covers which may help. Just having a hard time grocery shopping with his car seat in the cart or using his stroller. He is not a fan of baby carriers at all or else I would use that for sure! Thanks ❤❤
