Please bath with your baby. It is a great thing to do together when they are so young. It can be a pain to do every time, but I did it with both of my boys. Keep in mind babies, even toddlers, sometimes poop in the bath. Anyway, you will know when your son is getting too old for you to bath with him, but enjoy this sweet baby time. I never got one of the cushioned seats. Instead, I just used a towel in the tub. It worked fine and I saved money on something that I would have used for just a little while. Have fun.
