So I've noticed within the past two weeks that my son has started to HATE baths. He's never had a problem before and has been really happy, until now. I thought at first that maybe the water was too hot, but he's been screaming with every cooler bath we've had since then too. I even tried it tonight with a lot less water than what I used to do. I've noticed that he calms down when I stand him up to get his back. Do you think it might be that he just doesn't like the sitting position of the bath? Is it just a phase?
