Aidyn went through this phase as well for at least 3 weeks just recently. But thankfully has been fine about it again for about a week now which is good. Its pretty traumatic for him, as we dont have a bathtub, so he HAS to have a shower, which means most of the time we have to force him to have one whilst he is screaming and crying about it During those times if he's not really dirty I would skip showering him every 2nd night and just sponge him down... I just couldnt handle the stress. I have no idea what causes it, and no idea what makes him ok with it all again suddenly...???
