Thanks everyone for your responses. It's great to get some ideas.

I think we'll start first few days with bub in hammock sleeping in our room and during the day move hammock with me wherever I am (loungeroom etc)so bub can stay in it and then after a few days see if bub will sleep in cot in the nursery during the day time.
Sounds to me like it depends on the baby also so we'll just test it and see how we go
