When did you first spend time without baby?

I’ve been invited to an evening out next week. Little one will be 6 weeks. I’m most likely going to decline regardless but I do have PPA - is this my PPA or is this pretty normal? When did you first spend any time without baby? So far I was apart from baby for about five minutes to try driving again post birth but I literally went to the end of our street and back again. Other than that I’ve never been without baby but a couple of friends from NCT have gone for a coffee together without babies and some have had their hair done and so on. Am I being weird?

I do have a very involved husband who would obviously be caring for baby if I went anywhere on my own!
