DD is almost six months, breastfed, and pretty much a velcro baby - only naps in my arms (sometimes in the car seat or pram) and we have been bed sharing since birth as it's been the only way I've been able to get any sleep. We're doing this as safely as we can - DH is in the spare room, no duvets or blankets, sleep in the cuddle-curl position etc.
We have a Next2Me but despite weeks of trying, DD will not sleep in it. I can put her in it when she's already asleep, and on a good night she might stay asleep for an hour, but as soon as she stirs she realises she's not with me in the bed and yells until I take her in with me. I even tried a Sleepyhead in the Next2Me, thinking that it might help, but it doesn't matter - she still wakes up and wants to be with me.
At six months my first DD was transferred to a cot in her own room and it was easy - she was happy and that was that. I just don't understand how I can get this baby to feel secure and happy enough to sleep in the Next2Me, never mind a cot.
What should I do? I'd be so grateful for advice.
