Hi OP. All the PPs show you are not alone! We all have moments of frustration.
Let go of some of your expectations of being the best mother. We can’t always be perfect. We are human and sleep deprivation and lack of personal time can be really hard on our ability to stay calm. You’re triggers are not daft!
Have you read The book you wish your parents had read? It’s about knowing your triggers, you’re own experience as a child and how to build better relationships.
Have a word with your partner. Get them to have the kids whilst you do your make up. Can they have the kids for an hour in the afternoon when you’re needing a rest? Can they sort the baby bag and pack snacks for the day for you?
My OH would happily sit back and do nothing, but we have a set routine of things he does to help. I also find he is my biggest trigger. When he doesn’t help, or he’s upset me, I start getting stressed. He can see that now, and jumps in to help. Took a while for us to figure this out though!
The best advice I’ve ever heard is just to let it go. The stress, the worry, being on time. Slow down, don’t get irate when shoes aren’t on.
I also trust my older ones with the baby. Bath them together, don’t chastise them for being rough. My eldest loves to play with my youngest, and can be quite clumsy. I’ll quietly freak out and say careful etc. But the baby loves interacting and actually, he’s fine. He loves being tickled and brought into their games. It’s always safe. It’s me who is paranoid. I’ve let this go. Baby is a bit older now and they all race about the house playing games. They know his limits because I’ve guided them without shouting or interfering. Bring your daughter into all of it. She will love having baths with baby, helping pick out outfits, brushing their teeth together. And when you do your make up, do it with her. Show her everything you do. Soon enough she will be brushing your hair. These moments will mean more than playing dolls, I promise.
