The first 6 weeks or so with a new baby are tough going - no matter how we feed them. There are so many adjustments to make with a new baby, even if you've already BTDT with a new baby. Having two changes the dynamics completly. It absolutely gets better. I think one of the problems with swapping to formula is that most mothers do it when they percieve things are really bad. When things are really bad, they are going to improve anyway. Formula is introduced and the baby gets a bit better (which it will do anyway!) so formula is hailed as the hero.
Many mothers find this helps. Give your baby 1 breast for around 20mins (babe will probably be snoozing at that time. Gently take him off (he'll probably make a desperate grab at that stage and start feeding vigorously - but take him off anyway) Burp, change nappy and offer him the other side. He may take a little, or a lot. After than, wrap him and cuddle him until he is *really* asleep, then carefully put im down. Or if really unsettled, put him in a sling. No baby is going to *love* going to sleep alone at that age!
