Please be gentle as I’m feeling really guilty. I’m having difficulty keeping my cool when my three year old pushes my buttons. He’s just a normal three year old. But things like playing on the stairs/not holding banister when I’m walking down in front of him holding the baby, ignoring me when I tell him to hold on to be safe, being silly and not listening when I’m trying to get him dressed to go out etc. Getting ready to go anywhere (dreading nursery mornings!) I don’t scream and swear at him by any stretch but I’m often stern with him and can hear my voice getting louder and higher, making random threats like- I’ll take your toys away if you don’t listen, we won’t go to the park etc.
I get upset every evening and promise to do better but I get so irritated with him. I love him more than anything! I’m not sleeping well at the moment because of baby, and it’s a really unnatural situation being stuck inside due to lockdown, usually we’d be with friends, soft play etc. I know it’s hard for everyone at the moment and I’m not making excuses. I just feel I’m not teaching him in a respectful way, but stamping all over him with words when he’s only little 
Any advice welcome to try and keep my patience, I don’t want hun to remember his child hood having been unable to express himself or get told off too harshly for things!
