The Adam And Eve Challenge

I would definitely say the most helpful for this challenge is the tablet - I don't know how I'd do it with it!
Infants can get really annoying, so I love having the swing so parents can actually get some stuff done!
Walker and playpen are both extremely useful, of course - especially because they can teach your toddlers to walk and talk, so the only life skill you have to really do on your own is potty training!
