hi
My baby girl is the same - during the day she will sleep for either 10 mins, or 40 mins, then need to be rocked (in my arms) back to sleep, I'm getting a hammock from a friend this week in the hopes that it will enable her to fall back asleep in the day.

At night I'm still going to use the cot as she sleeps like a trooper all night (OK, for 3 hrs, then a quick b/f, then 2 hours then b/f, then 2 hrs and a b/f then up and at 'em!).... But I heard it was hard to go from hammock to cot when they got too old for the hammock.... I will let you know if the hammock helps the day time sleeps.
