Hey everyone, so my question is am I being unreasonable and/or over paranoid? I have a 4 month old baby boy who is currently teething, however my problem is my boyfriend (and baby's father) his daughter wants to mind our baby for the day, am sort of hesitant because she is only 18 (my boyfriend is 14 years older than me) and has never had experience with a baby, also she and her girlfriend both smoke weed. Am just worried incase they smoke weed whilst looking after my baby or don't know how to handle him when he's crying because of his teething because he cry's really loud and alot as he's in pain. If I say no my boyfriend and her will both hate me. Am just stuck in what to do. Am I just being a over paranoid new mother? Thanks in advance :)
