My baby is 2 months old and I go back to work in less than 3 weeks. My mom will be watching my little guy. What things do you recommend I buy to keep at her house? The less I have to take back and forth the better! She has a pack n play and is getting a swing with detachable bouncer. I’m taking over formula, diapers and wipes to leave there. And some extra clothes. She has a changing mat. He doesn’t take a pacifier. Anything else I should take or buy to leave there?? Thanks!
