I never did get the 3 or 4 day baby blues, but with 1 and 2 I did have a bit of a meltdown once I had been home for few days - with #1 it was over BF issues and I just lost it because I was so terrified of the toe curling pain of BF that I demanded he go and get a tin of formula and I slept while he took DS to town to get some and I felt better after that. With #2 it was by day 10 and it was just purely out of tiredness - I was feeding her well over 12 times a day at that stage and she was still demanding more and I just didn't have anything left to give her. Again I felt better after a half decent sleep. I never had it with 3 and 4.
