Putting my DS back in his cot for the 8th time in the last 30 mins. He's ebf, after his bedtime feed he falls asleep on me, wakes when I put him down, this is followed by 5-15 pick ups, falling sleeps, putting down, immediately crying episodes till he eventually will settles for a couple of hours. I need to pick him up because he just cries hysterically if I don't soon as I pick hi. Up he gets his suckle n drops back off. Any advices?
