Just received a letter on Friday night from the local health visitor wanting to visit me at home on Tuesday morning. I'm 27 weeks today and it's my first child. I'm a teacher and work quite a distance from home so a visit before the holidays isn't really practical. I have most of the baby things in but the nursery isn't started at all. Is it normal for a visit this early on? Also what will happen during the visit? Any advice gratefully received.
