This sounds really really crap. It’s hard and really boring, I’m an infant school teacher but the relentlessness is insane with little ones. I have some advice, take what you can/want and ignore the rest.
Give either the baby or the toddler to DH, so you can have a bit of time with just one of them.
Or give him both and just go out somewhere, on your own.
Have something, at least once a week, which is just for you. Make it something you can’t miss, like a gym class or a stamp collecting group or salsa or anything. He will have to have them and you have something to look forward to.
I am not going to pretend to know anything about your relationship but my DH and I nearly broke up at this point. I realised he didn’t feel confident with the kids and I wasn’t confident leaving him. He buried himself away and couldn’t see I was struggling. I had to talk to him all the time and we fell out a lot. We had a code word which meant “you are pissing me off, I don’t want to talk in front of the kids, we can talk about this later.” It worked sometimes.
If you have a garden put one or two of them in it. I have found many times that babies sleep better, in buggies, outside. My DS’s spent hours in mud. Hose them off before they come in or go to LIDL and get one of their amazing puddle suits.
Train your toddler with bribes, or whatever you need, to put things away. He has to do it at nursery. I didn’t do it. My sister has, it’s amazing.
Social media is the work of the devil. Most people are winging it and most people get really annoyed with their kids at some point.
Swimming tires everyone out. Send the toddler with DH every Saturday or Sunday. Make it a routine and it gives them a focus. Or give him both to him…or maybe not.
One weekend morning is yours, one is his, for a lie in.
I HATED it when people said it will pass, but it will. Ignore that if you like. You will realise at some point that it’s got easier. I think you’re actually at one of the hardest parts. I found 3 years way harder than 2 years and when 4 years rolled round I felt way better.
You’re doing an amazing job. You really are. You are a hero to them both and just being there is incredible.
Like I said, I have no idea what I’m talking about, just take what advice suits you and ignore the rest. Good luck xxx
