Yippee Peregrin! Did it last a second night or did the Curse of Sleep Club descend?
I was going to suggest, Dreaming, that you tell your medically trained DH, 'It just fell out, honey, honest!' 
Despite being in the throes of newborn-ness still, I can't shake the feeling of wanting a third. It's nice to be able to try things over again and not feel like a complete panicked amateur. I'm also loving seeing DS1 interact with DS2 - he adores him. As an only, I've never seen sibling interaction close hand, so it's fun. However, we'd need a lottery win to have a third, so I'm busily putting baby clothes on eBay and constantly reminding myself of how much I HATE doing laundry to talk myself out of it.
Well, we had a minor trauma yesterday
DS1 locked himself and DS2 into the car...with the keys inside and me outside. It was in the nursery car park, so we had a panicked half hour or so of the nursery nurses gesticulating through the window at DS1 to operate the key (I drive a Mini so if you're familiar with the key, it looks absolutely nothing like a key and has three buttons) while I tried to remain calm on the phone, alternately to DH and the breakdown service. DS2 was, of course, screaming his tits off the whole time as he loathes the car. By some miracle, DS1 managed to locate the key (after carefully tapping each of the normal-looking keys against the door handle, looking for a keyhole) and pushed the right button. Bloody miracle, but, if I was a drinker, I'd have had a double gin when I got home. Poor DS2 literally screamed himself hoarse. He had nothing but a raspy little squeak left when we got him out
Suffice it to say, I shall be a little more careful with the keys when getting the kids in the car from now on.
