Looking for suggestions for the bath. My 7 month old loves laying back and lounging in his skip hop moby bathtub however he’s basically outgrown the sling and he looks ridiculously uncomfortable when he’s trying to lay down. He gets a bit crazy sitting up in that tub so I’m not sure what our next stage should be. I don’t really want to just move to using the real bathtub because he’s pretty wild and I’d have to hang on to him the whole time. I could get a bath seat where he sits upright but he seems to love laying back. Are there any bigger tubs out there for this?
