I've been (nearly) continuously breastfeeding since dd1 was born five years ago - only break was from when dd2 stopped this Feb to when ds was born in June. So I'm an old hand at this.
But now for the first time I can see the temptation to bottlefeed - because I'm always worrying about ds feeding enough, and if I was bottlefeeding him I could see how much he is having. He is doing well and putting on lots of weight, but if he has Jeune's there is a possibility that things might change as his body outgrows his thorax and his lungs, and so I keep worrying. For example this morning he wasn't keen to feed for "breakfast" even though he hadn't fed in the night either, and then I immediately start to worry and think what's wrong etc.
