Baby Bathtime - Next Step After Sink?

Rebecca

Hi Everyone! My little girl has outgrown the sink for bath time but she doesn’t sit up yet, so I can’t just put her in the regular bathtub. We have one of those little narrow tubs that’s supposed to be the next step but I’m finding it really challenging to use.

What do you guys do? I think the easiest thing at this point is just to get her clean while I take a shower but I’m open to other suggestions.
