There is a reason for this and I've needed some time to think about it but...
My dp likes a drink (not in an alcohol dependant sort of way) at the end of the day. Usually a couple of beers or cider and he usually only has 2. At weekends he may have a couple more or maybe a spirit and mixer, still nothing I would consider particularly excessive.
I'm not a big drinker at all. I may have a couple if I go out however since having dd I'm very aware that I may be needed in an emergency and would rather not be under the influence and tend not to drink at home.
If dp has more than 2 he does change. Not in a nasty way but he will fall asleep on the sofa and be dead to the world and there are changes in the way he behaves. Once he's breached his 2 drinks he becomes useless for anything.
At the weekend I went out for a relatives birthday. I was driving home so had a small glass of wine with my meal but nothing more extravagant then that. DP stayed at home with dd.
When I got home I noticed smoke in the kitchen. DP said he's been cooking a pizza and fallen asleep. He'd woken up to the fire alarms going off and a kitchen full of smoke with dd screaming the house down as the noise had woken her up.
I'm seriously not happy for 2 reasons 1) he'd obviously had more than a couple of drinks and was solely in charge of our baby dd at the time.
And probably the more worrying
2) nearly burnt the bloody house down with our dd inside.
I've known him to actually sleep through a fire alarm going off before now (steam from the bathroom sets the one on the landing off of you leave the door open after a shower).
So am I being unreasonable to say to him no drinking when he's in charge of our dd?
