I am embarrassed to say that I was reading your comment at 11.30pm, with an asleep son n active daughter crawling all over me. 

I think on the whole, I’m getting more disciplined about not looking at my phone before bedtime, though. Yes, I will prioritise sleep.

Great advice. Sleep while we can. My wife is sleeping now while I’m having my breakfast with two bored kids (I fed them breakfast first haha)

SN Defying Conventional Parenting Advice

I looked briefly through your other posts and I can't believe no one has suggested the most obvious:

Get some sleep.

Biggest hack for everything. If you have some free time and the kids are awake, go take care of them so your wife can take a nap. Or if she has energy, do the reverse. You're sleep deprived when you're a parent, especially with young children, so prioritize the one thing you're not getting.
