I've recently found out I'm pregnant with #3. We have a 3yo and a 1yo. My husband wasn't working when I was pregnant with #2 so was able to look after #1 when I had my antenatal appointments. This time... well, I don't really know what to do. Has anyone taken young children with them? They're very well behaved and they wouldn't mind being sat in the buggy in the room with me, but I think the midwife probably would and for some of the appointments I certainly would - my 3yo has very sharp hearing and an excellent memory! I wouldn't leave them in reception, though, even if I was allowed. I think they'd be upset by that.
I'm pretty sure the answer is going to be that I have to ask DH to take a half day off for every appointment, but how have other people managed antenatal appointments and already-existing children?
