Toys: Squeeze Toys / Water Variety / Bath Crayons: all of these help keep Caroline entertained when her and Carson share a bath. They are perfect for her small hands, great for skill building, and aren't too messy (I'm talking about the crayons).
Baby Care: I'm an avid user of Johnson and Johnson products...they are easy on the wallet, smell great, and are gentle for my girls' tender skin. Can't lie-I've tried some of the pricier brands out there and always seem to revisit the tried and true J&J as I know I won't be disappointed.
Washcloths / Towels / Mitts: We love the RH Baby and Child hooded towels for post bath drying. They are way absorbent, large in size, and have fun details and accents. We also use some made by Carters which are great, too.
The Other Essentials: Trying to maintain a safe bath environment is SO important, especially when I'm juggling two under two and praying no one bumps their head, falls, or has a total meltdown. We have the bath faucet cover which has saved us from a few bumps, and bath mats are great for when someone (i.e. Caroline) decides she no longer wants to sit. And those sweet rubber ducks with the heat indicators on the bottom are ever so helpful when they are teeny tiny newborns and you have no idea how hot is too hot. ;)
