Me, 31 weeks with No3, who is a boy, I have two girls already, aged 4 and 2. Closeness of spacing reflects my age more than anything else, although found this gap quite doable with the girls. I have a two bedroom house, but one of the bedrooms is big enough to split into two, so ds will have his own room, with the dd's wanting to share anyway, so they'll be in bunk beds.
I traded in my 4 year old Zafira for a nine year old Ford galaxy, have played around lots with the seats, and what would have been a nightmare of skinned knuckles in the Zafira is a dream in the Galaxy. Bonus feature is it's much nicer to drive too!
Holidays always fine too, as we go and stay in the inlaws Hebridean House, or rent apartments etc.
Pregnancy has been much easier this time round too, in terms of less nausea and sickness, but I am absolutely shattered all the time, and this will definitely be my last, it's just not fair on my other kids!
