We LOVE co-sleeping in this family as well. With my first, Chloe, she slept with us until 8 months, when she moved into a hammock (which she loved and took to straight away). She stayed in the hammock until she leared to do a sort of front somersault-dive out of it (time for new arrangements) and she went straight into a cot at around 13 months and began sleeping all night. We are sharing our bed at the moment with our other little angel who is 9 months old, but she can already do "the dive" out of the hammock so I think she will just stay with us until around 14 months. It is sometimes a little challenging to get good rest, particularly when bubs are teething (like at present) and where she wants my nipple in her mouth ALL NIGHT!! But we love it overall and I know just how quick they grow up and move into their own space and that precious time is gone forever. I feel sad even thinking about her moving out of our bed!! Enjoy. Listen to what feels right and again......ENJOY.
