I recently transitioned my DS to formula after much stress and thought during exclusively breast feeding. I wanted to make it at least six months breast feeding. I got my period when he turned 2 months and now he is 3 months so since I got my period he fusses at the breast, feeds every 1-2 hours, and seems very gassy. So we decided to transition to formula. He is better and goes up to every 3 hours now. Less fussy and less gassy. more happy. Question is this same thing happened to my daughter two years ago I got my period and breast feeding became difficult. so we got her on formula after much trying and stressing as well. Can getting period affect supply/milk in any way? even now I pump once a day for comfort to wean my breasts and when I give him that milk once in the morning he gets gassy and fussy
