Hi Hayley - hopefully you're still checking this thread....
Is your bf working away in one place, or all over the place? If he's just in one place, and you want to move to a rented flat anyway, then why not just move to wherever he is working for a few months. I'm assuming that your first isn't school age yet, as obv this will be harder if he is.
My dh works abroad during the week every week. He took a couple of weeks off when I had dd, but then was straight back to it. It can be very hard work sometimes, but you do get used to it, and it sounds like you have lots of family around you to help if you stay where you are, which must be a good thing.
Tbh, most dads probably miss the 'firsts', as they are at work during the day anyway, as are many mums!
Glad to hear that the worries about the birth have been resolved though .
