same as a lot of other posts - 22 month gap, boy then girl.
as we were building up to it, it felt fine - 2 years is a fairly standard gap, but the reality of the first few months was hellish - 2 lots of nappies, very little sleep and no quality of life. I can remember sobbing trying to read ds a bedtime story (something i had loved doing before dd)and realising that this special time was never going to be the same again...
BUT - that was the first 3 months. she settled down well, story time retsrated properly (half an hour later, after dd had gone to bed) and life got back to normal.
now when i look back at photos, ds was really only a baby when she was born, and i do think it has made him grow up faster than he would otherwise have done.
similarly, i do wonder whether dd has had all the attention she has needed. her speech is still pretty limited at age 2.5.
BUT - they are actually best friends already and barring the occasional spat, they play nicely together and look out for each other.
my sister and i are 4 years apart and i don't think we were ever this close as children.
