Oh god, horrible sense of 'me too' here. I hate hearing myself when I'm shouting a lot. DS is 3 and a half and pushing the boundaries, DD is 14 months. The house is always a complete tip, if I tidy up everything is pulled out again in no time.
Most evenings I'll vow to myself not to get angry or shout the next day, then it all goes downhill again.
I'd say a lot of DS's bad behaviour is down to jealousy of DD, that and her taking his toys now she's walking about. I can understand he gets upset if she takes something he's playing with, so he hits or pushes her, but what really gets me furious is when I hear her crying, go into the room and he's hitting her or squashing her or something and laughing. I send him to his room as punishment, but that doesn't really work, as he'll just read a book, and then DD wants to go in there after him and starts crying herself!
Mme Lindt: my DS went through a running off phase too, but stopped after a while. I did threaten to get some reins, but I'm not sure if that was what did the trick.
DS also went through a phase of putting his hands over his ears when he didn't want to hear something. When DH asked him about it he said it was to 'make the cross go away'.
What's worse is that DH and I shout at each other too, and I hate the kids hearing us. I didn't use to be an angry person, believe me! We are under a lot of stress at the moment, and tiredness makes everything 10 times worse.
Some times I've said to DS let's start the day again, and have a kind and happy day, you listen to what I say and don't do naughty things, and I won't get angry or shout. That does work sometimes.
Sleep deprivation is such a big part of it. The CIA use it as a form of torture you know! OP: 4.30 wake up sounds awful. I totally agree that acceptance really helps with things like, yes the house will never be tidy, yes, toddlers don't listen, yes babies do throw their food on the floor. However, you might be able to get your LO to sleep later. The best book I've found on sleep is Teach Your Child to Sleep by the Millpond Clinic. It's evidence-based, not some nanny's theories. It does have a whole section on how to deal with early waking.
Here's to a calmer day today.
