My LO after sleeping well for 14 weeks, at 15 weeks her naps have reduced down to 45 mins, she is also taking 1hr to send to sleep for naps & nightime. I am going to try her on the 4hr EASY as she has been on the 3hr but bearing in mind by 08:00 in the morning she is yawning and looking sleepy! I think I must be reading the signs wrong, and I thought I knew my daughter! Not sure if she would be able to cope with a longer activity time, not sure what to do, all very confusing!
