Sean has been getting a bath with ears submerged since he was two months old, and he is now 10 months old. He is fine with it, and it is working out fine for him...No infections, all checkups have been good, great ears on the boy. And you are right they love it. I tooo found it hard to put the baby in the bath set because they didnnt like it. And he was getting bigger and wanting to play with his toys and stuff. I hope that this helps.
Dont feel dumb, we all have questions
