Not got much more advice than what the others above have said except to say that it is early days yet and whatever you are doing now must be the right thing (even if it feels like it's one long nightmare).

Nobody told me how blimmin' difficult the whole breastfeeding thing was - I had problems getting my fidgety little bundle of joy to latch on in the first 3 weeks but after that time and when he put a bit of bulk on it all got a lot easier and we found our routine.

Don't despair.
