My 7 week LO is mixed fed, I give her bottle at 11pm and she sleeps to say 3,4 or sometimes 5 when I breast feed her, she then sleeps for another 2-3 hours but during that time she is so fidgety and noisy breathing with straining sounds etc. I think I wind her ok and oddly this is only time in whole day that she does this! Divi think she is hungry in her sleep??
