O.k. this is not good. And you know that. But this is easy fixable.
I have been in a very similar position myself. Ill myself, sleep deprived, ds1 really pushing me more and more over many months.
Lets have a little look at whats REALLY going on here.
Firstly he's very tired and overwhelmed, at starting reception. So are you. New playground mum friends to make etc. Your dh away.
He needs lots and lots of love and care at this transition time, of starting reception.
But, you do not have that to give. Because you are tired and fed up.
1)You need a treat. something nice. favourite chocolate. Go and quickly gets nails painted for £8, on the way to collect ds1. OR something. some sort of treat.
2)Then you need to get to bed. Sleep. during the day more. screw the hoovering. rest more. And put ds1 to be early. And working around dd2's feeds, go to bed yourself As soon as you possibly can. even if if you are getting up for nightime feeds. YOU NEED MORE SLEEP. Everything is much more manageable, if you have had more sleep.
3)And , it is irritating when they won't get their socks on etc. But take a step back from this. Is it really that important ?
Do yourself a BIG favour. get up 10-15 minutes earlier. Get yourself ready. then dd. then ds. And then Make sure, you have 5 minutes, to actually sit down, and relax. when you all ready, before you needc ot leave the house to do the school run. instead of rushing and shouting at everyone, "come on, come on".
The reason why you get yourself in the sock scenario, as I do myself, is because under your breath(or actually saying it, as I have done), you're saying. "just put them on. do as you're told., stop mucking me about. I don't have time for this nonsesne."
And thats because you are under time pressure. But if he had done this 15 minutes ago, you could have , laughed it off, "come on you cheeky monkey, I'm gonna chase ya, till you get them on, here i come, here I come". Laughter laughter.
So don't allow that time pressure.
Compare the 2 scenarios.
Are you gettign what I am saying ?
