How long will 6 month sleep regression last? Is it possible to get this at 7 months? My baby is still learning to crawl and sit up on her own now. I give her plenty of time to practice. Still having sleepless nights. Please help.

A. the sleep pattern usually improved by two years of age sleeping pattern in small children changes from time to time but will improve with increasing age of the child and you have to just see for any environmental factor which is affecting the sleep like temperature variations as well as the child might be having some digestion problem for breathing difficulty due to nasal blockage has to be looked into
