Remember your sunblock ladies and gent! Don't slather the kids and forget yourself!
Well. Don't know where to start actually. Might do a few posts and split things up.
chasing I missed the hi-5 ing so please accept this as an alternative. Plenty peeps have also given reassurance about how you are now feeling. I hope that you can relax and embrace the feeling of oxygen rushing round your body - all that time holding you breath must have left you deprived.
stunt you are so pragmatic and empathic - reading the way you describe your DH and the causes for his behaviour is quite emotional. Your DH is very lucky to have such a patient and sensitive DW. I am sure you are right that once sleep becomes a regular feature of your household you can all start working on being a proper family again.
WTF MM!? I just don't understand your SIL's behaviour. Why would she contact you twice to say all was well and then lose the rag? How bizarre. I could forgive the dirty vest and the sleeping on BIL if they had had a lovely time. You know what I mean? If they had all just been playing and enjoying themselves I wouldn't mind about the other stuff. I also wouldn't mind about the crying - babies cry and can be really hard to settle. But the accusations and name calling? WTF?
Here is my theory. They were having a lovely time and enjoying themselves, forgetting or ignoring the guidance you had left. Then things start to go a bit pear shaped, M gets overtired and hysterical (and we all know how distressing an overtired baby is) just as you text to say you are coming home. Panic sets in as they realise hey have no idea how to cope now and you text to say you will be back early. Your SIL realises how wrong thing have got but can't accept responsibility so blames you and M.
Accepting this as being the case here is what I would do. I would leave them a wee note thanking them for agreeing to sit for you . . . Bear with me! Say that you are not quite sure what happened but it is clear that everyone is pretty upset. I would explain that You are hurt by the references to M in a negative way and that you cannot accept that she is to blame for whatever happened. Then, maybe I would conclude with a kind of invitation for them to get in touch should they want to talk through the evening.
As I have said above, I would forget the lack d sleep suit, the dirty vest the lack of grobag. Leave it behind. Those things don't matter. What matters is the nasty accusation and cruel references to your child. My suggestion above I suppose also only stands if you have any interest in salvaging a relationship. If not then forget them.
VQ I have yet to visit the Falkirk Wheel. We might take a visit soon. Maybe some of this lovely sunshine will burn off the bugs, germs and snot from Valium towers.
I am not sure quite how you avoided 'accidentally' waking DH! That is one mega-snooze! Even after a boozy night I am not sure I could ever have slept that long on the sofa.
