My dad is keen to be a hands on grandad to my DS, and when he comes to stay (long drive so stays 1 or 2 nights) he likes take care of the evening routine and putting DS to bed. This is great and I'm appreciative of the help, the only thing is my dad gets in the bath with DS. I'm not sure this is appropriate though, especially now that DS is getting older, 6. Keen to understand others views on this
