I have a 26 month old son who sleeps with my husband and I, all three of us are very content with our arrangment and love being together. BUT I am expecting a baby girl in August and I really want her to join us in the family bed. I am just worried about my son rolling on her, or her waking him up when she fusses at night. I was thinking about using a sleep positioner (with firmer sides) to prevent him bothering her. Does anyone have any suggestions? How do you co-sleep with two children? Any advice would be greatly appreciated!
