Hi can anyone help my son has never been a good sleeper he use to wake every 40 mins through the night until 7 months when I did sleep training and now he will wake here and there which is way better than before, the problem is he wakes at 4 - 4.30 for the morning and won’t go back to sleep. He goes to bed at 6.30 and has 2 naps in the day one at 8ish for 45 mins then one at 12-12.30 for 1 1/2 hrs to 2 hrs. He settles himself to sleep for naps and bedtime (has a dummy but can find it now). Does anybody have any advice? I can handle 5.30 but 4 is not reasonable. Thanks
