Oh now it all makes sense!!!
I bottle fed DC1 after failing miserably to establish breastfeeding, but did Extended BF with DC2.
I though it was all about the support I had, but it turns out that its because I was brought up working class, but have since got a middle class job, so it was all down to my class, not the support. Basically, DC1 is bluecollar baby and DC2 is a bit posher.
God if only I had known this before I wouldn't have been so upset when BFing went so wrong first time. It must have been because my facebook picture made me look working class. I've since updated it to a photo of me at a wedding where I look a lot more middle class.
From now on, DC1 will only wear primark, but DC2 will get Boden, oh yes!
Halleluhjah! I have been truly enlightened!
