My husband and I are meant to be going on a date night we have tickets to watch Mickey Flanagan but I think my baby (7months) has his first tooth coming (I can feel it under his gum). I've said I don't want to go but husband is saying I'm being unreasonable and that his mum who is meant to be babysitting is more than capable of looking after him. I don't want to go in case he's unsettled and needs me to go to sleep. Am I being unreasonable? Would it be fine to leave him because it takes a few days for the tooth to cut through?
