With my first 2 dd's I got it 4 months pp and was EBFing. My twins just turned one and I haven't gotten yet with them (although I do notice a monthly hormonal/super-emotional thing going on but no bleeding).
EBF'ing 'round the clock, 1st baby, 39 yrs old - got AF back at 11 weeks pp : Oh well, we decided to TTC w/close spacing, so I was preg. again by the time DD was 5 1/2 months (so much for my hopes of using LAM as bc!)
I got mine exactly at 6 mo. then haven't again. I guess irregularity is typical. I was freaking out so I took a test yesterday but it came back neg. whew! My friend who is in a midmifery masters at yale said hers didn't come back til 21 months so, who knows : )
4 months this time, EBF my baby and nursing my two year old round the clock. i could almost say he is EBF too, but he did have about a quarter of a cup of yogurt yesterday. it was somewhere around there with my other two.
With my 1st, 10 months; with #2, 6 months; current dd is 5 1/2 months and so far no AF.....but I have felt really crampy lately, hmmmmmm. I was hoping for a year, but I have a feeling it's coming soon : . My dd nurses every 3-4 hours.
