Blimey folks, there's a lot to catch up on here....
If you want to share your plan Oi, and get any more advice or suggestions then please do. It sounds like he's at the start of a spiral, so tackling it now is the best thing to do.
But remember- strong and brilliant as you are, the stress of keeping it all together, of running the house and coping with issues like that, and working, and just the overwhelming responsibility have the potential to cause you problems/illness: I speak from bitter experience. Keep talking to your friends, and on here, and if you can get anyone to take up some of the slack as well, do.
I know everyone else has said it, but your FIL is a fool Cherry, and his son equally so. I'm working on getting every flavour known to humanity down DS whilst he'll still take it.
I can understand you feel embarrassed, but as you said, it's his bad behaviour not yours. I think the short-term plan to tell him to F-off when he next pulls that stunt (or something more ladylike!) which I bet would shock him into brief good behaviour and the longterm plan to save up is a good one- I know several ladies who have secret funds for that, and it will at least give you confidence.
Kitty may I recommend for your pots possibly fuchsias (ours flower til December), and also possibly asters, both are cheerful and depending on size several can be bought for £13.
Love the phrase 'lobster hands' mopsy that's brilliant! DS loves doing it too, although a little too hard and ends up nipping you which is bloody painful when you're bf-ing him I got our baby toothbrush in Waitrose ironically: we seriously don't have any round here, but found one in the shop near my Dad's, and like many on here DS loves his! Favourite part of getting ready for bed.
So sorry about the sleeping Gee- do you think the dizzy spells could be connected to the lack of sleep? I'm amazed you cope, I know I'd be in a heap on the floor, never mind feeling woozy....
