My favorite part of going to the doctor to get a new cast, was being able to bathe my baby boy. I had no shame, I walked right into that doctor's office with my baby bathtub in hand. I didn't care how much stuff I had to carry... diaper bag, breast pump, lunch for my toddler, whatever... I was bringing that tub!
Merritt's first bath was given in the doctor's office :)
TIP: Your baby's legs will be very sensitive from being in the casts. I used very gentle soap with no fragrance and a super soft washcloth. I never applied any lotions to his leg. What to bring to the visit: tub, two bath towels (just in case of a little squirt!), baby soap, washcloth, and 2 clean changes of clothes (sometimes putting the cast on can get really goopy.)
