Terrible horrible day with my DC today, I feel so sad and cross this evening and really need help to make tomorrow better
, sorry this post is long.
DC are 5 & 2.5, eldest is really really whiney since the school hols started, will whine and whinge and complain about ANYTHING it is really hugely exhausting. I have tried talking about it when we are both calm, explaining that it makes the day / activity less fun for everyone, that it makes everything harder etc, and we agree to try not to do it any more, and then the next day it just starts up again. First thing in the morning starts whining for TV to go on, and I feel like our first interaction is me saying 'no' which sets us off on totally the wrong foot. DC1 has a knack of starting to whine just as DC2 is up to something, which brings me onto DC2...
Younger DC is at the brilliant age of tantrums AND potty training. I find potty training utterly utterly dispiriting and knackering and awful. I know i have to just get on with it but i honestly HATE IT. The tantrums DC2 can pull are extraordinary - today there was one that lasted a full hour (i timed it) all of it on crowded public transport during rush hour complete with eye-rolling commuters and tutting old ladies. I generally go down the route of calmly explaining what is going to happen / the rewards for good behaviour / reasons why we can't do what she wants right this minute etc. and then I try to ignore the tantrum but DEAR GOD A FULL HOUR!?! A one point I was leaning against the tube door just crying and crying and not knowing what to do, it was horrific, she was writhing out of her buggy, hot tears, bright red face, yelling blue bloody murder. Horrible. When she starts I feel like there is nothing I can do to contain it, it just has to run its course, but the tantrums go on FOREVER.
Today was hard because I had (probably very stupidly) gone to meet a friend in a town about 2.5 hours from home (old old friend, don't see her often, she has a new baby and I was desperate to see her, this was the only day we could do & I had both DC with me unfortunately). The journey was really long and difficult and involved lots of trains but we made our way there really pleasantly doing activities on the train, having snacks, chatting, playing etc. when we arrived the whining started from DC 1 and continued all day which made it really hard to talk to my friend about anything, and exhausting to deal with all the time. Then they both has a little sleep on the way home which I thought would mean they'd be refreshed for the final slog across London, but It was just awful, with DC2 tantruming all the way home. I completely lost it with DC2 when we got home and she point blank refused to wash her hands for dinner, I really really yelled the bloody place down. it ended this evening with me just sitting sobbing in the kitchen with both kids saying 'why are you sad mummy?' DC1 wrote me a note saying 'we love you mummy' which just broke my heart
and then later on before bath said 'I have an idea mummy, I will do your jobs for you and then you will feel better' 

I am clearly utterly crap at this parenting thing. I honestly do start the day very bright and breezy and full of great ideas and love and good intentions and they just wear me down so so much.
How can I hold onto my temper with them? How can I not lose it with them again? I feel awful when I yell, I never used to shout at all before, but now I feel so often right on the verge of going completely mental at them. I obviously need help, it feels quite desperate and I am scared and appalled by how cross I can get with them and how out of control and helpless I feel
