My 6 month old (second baby) learned how to turn over last month. Since learnign he has now taken to doing it in his sleep. Unfortunatley he will only sleep on his belly - we've tried very hard to get him to sleep on his back and on his side but he just won't. Now the problem is that he flips over from his belly on to his back - and then can;t get back to sleep. This has become a real problem as I am back at work and he's "flipping over" about 10-15 times per night and I have to get up to "flip" him back on to his belly. Have tried letting him cry it out, have tried rolling up a towel/blanket alongside him to make it more difficult to turn over - but nothing has worked! Any ideas?
