He's actually 11 months old. Mummy usually makes him sleep at night by breastfeeding and rocking alternately. If Daddy (that's me) tries to make him sleep, he starts to cry, and cry and then vomits. Sometimes an Auntie can make him sleep during the day for naps, but not always.
We've read all the advice about Mummy being out of the room, or out of the house (not going to happen), but how does that help if he doesn't go to sleep in my arms, or on the bed, or in the cot or anything I've tried?
He also wakes every night and isn't comforted if Daddy tries to hold him and sooth him, he only goes back to sleep by breastfeeding.
We're never going to let him cry it out.
Advice please?
