My husband and I both bathe with our daughter, it just makes things so much easier. We started bathing with her probably when she was about a year old, basically when she no longer had a fear of the shower lol. My husband told me he'll probably stop once she's about 3, but her and I will probably bathe together until she decides she wants to bathe alone.

I stopped bathing with my son around 3 maybe sooner. once we started talking about body parts and such. once he began to poke and laugh at me lol.. he still showered with dad since they obviously have the same parts but he then started the poking and laughing with him..

My husband still takes baths with our 7 month old. I think as soon as they can sit up and able to be fine in the water by themselves without falling and cracking their head off the side of the tub is a good age to stop . At least that's what we are going to do .
