First time in the BIG BATH

We have been bathing Zuki in her infant bathtub for a long time. Last week she started twisting around so she could sit in a way that she could splash around, and it made it hard to wash her, so we do baths in the big tub now. She is loving every minute of it, splashing and trying to slide all over the place. She has face planted a couple of times, it scared me to death, but we keep a hold on her the whole time, and she cries when bathtime is over. I am finding that 10 to 15 minute baths makes her very tired, and she goes down easier and is staying asleep longer...hopefully soon she will be sleeping through the night...still waiting.
