Ever since her first bath, I have used the same technique with Ava and it works every time. Before I get her in the tub, I cook some chicken in olive oil, cut it into small pieces and put it in a bowl. I get the whole bathroom ready (towels, tub, shampoo) and then I tell her to get into the tub (the first time I had to lift her in). Once she is in the tub, I start to wash her, and she gets little bits of chicken every so often throughout the whole process. It is the only time she ever gets chicken, so it is a huge incentive for her to behave during bath time. It's a process that has worked every time, so I highly recommend it!
