Well, as someone who's already got one little 'angel' running about, no, you do'nt get a moment to yourself, getting your fanjo waxed suddenly counts as 'me time', you will also find yourself spending 'me time' cleaning the bathroom as that's the only time you'll get to do it without a charming toddler trying to 'help'.
However, DS can now say "how do you do?" this is heart meltingly gorgeous and I want him to have a little brother or sister to share his life with. Just not now...
We had another scary conversation the other night, we are in an area with a very good, very over subscribed state primary school, the other schools aren't very good or are a hell of a long distance away, so bullets will be bitten, prep back up plans are being made - we're going to put his name down for prep and pray we get into the good state school! Thing is, half way through this DH said he didn't understand why I was stalling about one of the very good preps - it's all boys, I said but what if we have a girl next and I'm having to do 2 different school drop offs before getting the train to work? DH said, but we want to find out what we're having this time, so we'll know by the 20 week scan, so we'll know before next summer if it's 1 of each or two little boys - at this point I had the Rolf Harris song in my head and burst into tears that by this time next year I might have 2 little boys of my own. (google it, you will be crying by the end of the song)
That ended sensible conversations about school fees (FYI - less than paying for nursery full time! Nursery is sooooo expensive!) and moved on to a conversation about names that work well with DS's name, did DH think that this yet to be conceived child would get on with DS, did he think they'd grow up close, when would be a good time to take them to disney land so they are both an age to enjoy it 
etc.
