My baby kept on not sleeping well until he is twelve months, he even wake up every one hour which make me and my husband very frustrated, but start from the ninth months, he is getting better and now, he is twelve month and weeks, he can sleep whole night-- ten hours, before that I have give him several time珍珠末,I am not sure whether it works, but anyways, don't worry, he will be better when he grow up,moreover, you can see whether he felt too hot as baby cannot sleep well if he feel too hot!
