I don't think it's wrong.. Everyone has the baby/bath pictures. They are memories captured forever. However, I think it's a little irresponsable to be posting them all over social media,maybe not babies per say, but I see a lot of 3-5 year olds in the bath/or pool nude or semi nude on social media. You may think it's cute and innocent, but you never know when a child predator will see it.
