Bath time

My husband and I have a difference of opinion on this subject for our son (3) and daughter (8 months).

Right now I tend to bath our daughter in the kitchen sink while my husband baths our son in the shower. We both bath both children so this isn’t a gender thing. But my husband had worn swim trunks when our son was first using the shower and shower with him. Now our son is big enough to go in himself and my husband stands on the outside.

Our new house will have a tub. I got my daughter one of those baby seats to sit in. My husband doesn’t think they should bath together. But we came to a compromise that they both have bottoms on and we will clean them right before they get out.

Is it appropriate to bath brother/sister together or siblings in general? To what age? For my husband I think it’s more a privacy thing. I didn’t think it was a big deal but curious what others thoughts are.
