Girls will be here for ds1s birthday. I can't wait! 
I had a 2 year 3 month gap between the girls and then the same between the boys. I had a double P&T and then a Bugaboo Donkey respectively. I walked a lot, particularly with the boys and it was brilliant. I couldn't have down without a double buggy. I sold it when we move here as I have to get I. The car to go everywhere and DS1 is older now. I can trust him not to have to be strapped down in a shop.
I know the bugaboo was expense but it was great as I could have pram thing and regular seat, or car seat and regular seat, or two regular seats and I could flip both of them away, both to me or different ways and it was narrow enough to go through most doors. It also did a funny flippy thing so you could pull it through the sand or snow.
And also....finally....they hold their price if you look after them and sell for a decent amount.
Annnnnyyywaaayyyy, a fab day chilling with the stunts or the nuns
For 5 boys hanging around the place we actually did get to chat, drink copious amounts of coffee and generally visit. Mini stunts are fab and DS1 was most Disapointed they had to go home!
