Alright this may be a dumb question, but I can't figure out how to grocery shop with lo. He's 8 weeks now, but we only have a graco 4ever convertible seat, so we don't have an infant carrier to put in the cart 🤔 we have an ergo but I'm not super comfortable with it yet, and I can't clasp it shut without dh 😩 are there any others without an infant car seat that have managed to find a way to go shopping!?
