Travel that's so lovely of her, you're so lucky that she's helpful and you get on. I couldn't have imagined anything worse than having my ex MIL MW there at the birth, she was calling the hospital asking for updates at 1am on the night DS was born and was about to get in the car and force her way in! Bit of a nightmare and very pushy! Having said that, if you get on with her then go for it, you could probably have two birth partners couldn't you? DH and MIL? Pleased you got to hear the heartbeat though, that's great news.
Rainbow I had mine confirmed this week too, 19 weeks on Monday and I'll be off for a year - can't wait!
