My beautiful 4 month old girl has always had massive problems sleeping during the day even as a newborn. After a lot of very hard work she now has three naps a day but wakes up abruptly after forty minutes however tired she is and however much or little sleep she has had at night. This would be fine if it was all that she needed but she spends the afternoon screaming with overtiredness and is impossible to settle. If she manages to get a long sleep at lunchtime (if in the pram pushed very fast without stopping) she is a lot calmer. I try all sorts of things to help her sleep longer but have had no success! I just feel like a complete failure and a terrible mother- there must be something I can do to help her and stop her being so unhappy all the time.
