I just would like to hear your opinions on Step siblings / siblings and boundaries. I have a two week baby and DSS age 15. He asked if he could bath her and I didn't like the idea of this mainly as I'm just getting used to it myself, so I said he could help. He happened to not be around when I bathed her early morning before visitors were due. But afterwards, it got me thinking, I don't really want him changing her nappies and bathing her. Am I right to feel like this. DSS is high functioning autistic so as to not drip feed. I'm really trying to make him feel included.
