The plastic tub we got does not fit in our sink. I bought a big "bath sponge" but already tried that out and don't like it either for her to sit on it and me to support her head/neck while trying to bathe her. I cannot but the plastic tub in our tub b/c I cannot reach over the tub to bathe her yet due to soreness from my c-section. So, I am still giving a sponge bathe and then wash her hair over the kitchen sink,,, would love to hear what you are doing at this stage. Thanks!!
