here's hoping you can help.
DS has always been a fantastic sleeper, sleeping through the night from 11 weeks old. He has slept through teething, colds, sickness etc.
About a month ago my MIL came to live with us and since then DS's sleep patterns have been totally up the wall!!! He will sleep one night from 7.30pm - 8.30am the next morning and the next night will wake at 4am . I feel as if we are on a slippery slope and that things are getting progressively worse.
I have limited DS's sleep to 1.5 hours on non-active days (i.e the days he stays at home) and to 2 hours on active days (days when he goes to nursery). I have caught MIL allowing him a nap in the afternoon in the pram but have discussed this with her and she swears that he is not sleeping away the day!
I am at my wits end. Any helpful hints would be most appreciated.
BTW - his room is totally blacked out so I know that this isn't the problem.
Thanks in advance
