I know gender norms are crap but I think this is a bit far, I'm guessing she purposely brought these to prove a point. DS does have a lot of blue stuff and there isn't anything pink in sight, I don't know really, I just buy what I like while he is so small. If he liked them I'd buy them for him but he's so young and doesn't have a preference yet so it seems stupid to purposely buy pyjamas that are aimed at girls.
AIBU?
These are the ones btw:
