0-1 Was wonderful. DD was a very easy,sleepy baby so apart from 1st time mum wobbles, it was fab.
1-2 Worse than 0-1 but only as DS is not as laid back as DD.
2-3 We are trying to decide at the minute about 3 but I think the 3rd will just slot in.
It obviously depends what type of babies they are and age gaps (there is a 3.5 gap between mine) and babies are always more work than older children so by the time a 3rd comes along the 2nd is more independant. This might just be wishful thinking though.
