Now of course, before anyone jumps down my throat, I have all my sympathies with them.
The situation is as follows. Both dh and I work full time. I get up at 6am and leave between then and 7am (long commute). Dh can sleep till 8am and then get up and go.
For the last year, this boy has woken up between 1am and 3am and screams v v loudly and constantly. They don't go to him till about 6ish when (according to his mother), she takes him into bed with her and they go back to sleep till about 10/11ish.
Now to me, it's pretty clear that this is what might be causing the issue (the sleeping on in the morning). He's their first child, the father sometimes works from home or works away so if he's there, they all sleep till 11am.
However, I am horrendously sleep deprived. So much so, that I need to drive today but can't because I am sure I will fall asleep at the wheel. I have fallen asleep at work and in the loo and teachers at school commented on how dd looks like she has 2 black eyes she is so tired!
We have tried ear plugs, moving the rooms around, white noise etc. but the fact of the matter is, he's large now and the noise is huge. We are in very narrow and small terraced housing (only 2 beds) so it is impossible to escape.
She (the mum) does speak to me about his lack of sleep. I want to (kindly) drop into conversation that the morning sleep might be causing an issue or even lend her my Ferber sleep book (if I can find it).
Dh thinks we shouldn't interfere (I know he's probably right) but I am so exhausted now, I think it's starting to affect my state of mind a bit. I'm snappy and feel a bit down tbh and have started trying to go to bed at 9pm to at least get some respite which is making me feel I don't have a life as I only really get in from work around 7pm!
