My worst experience was probably when my DD1 was a few weeks old. I struggled to breast feed and suffered severe PND. I was in a mothers room at a shopping centre bottle feeding her and two older mums walked in (by that I mean older then me- I was 18 and they were mid late 30s). The whispered to each other for a while, then one looked at me, frowned and said "don't you know you should breast feed your baby?! Not that you should have a baby anyway". I stopped feeding DD1, packed up my stuff and walked out, left the shopping centre bawling my eyes out.
