It's really difficult.
I had to learn to be a parent all over again with ds2, because he is such a different child. When ds1 was four, he still wore a wrist strap near roads - Ds2 can run as far as my voice will carry, he will not go in the road.
I have overparented Ds2, because it's either do that or let him feel neglected. It's been difficult for me to learn to give my attention in a way that isn't a safeguarding supervisory exercise.
Ds1 likes me to undress him, and always has. the battle is getting him to dress himself (he sometimes finds this hard) Ds2 likes to dress himself, and has self made 'rules' about what I am and am not allowed to help him with. he frequently walks to school with his shoes on the wrong feet because He Is Right.
Ds2 likes to sit at the table with me. And talk. This is ds1;s idea of hell on earth - sitting and conversing? no no no! It took me ages to realise that Ds2 notices and is hurt if I don't respond to his ideas and opinions (oh the guilt) but you see, I had got used to ds1's monologues, in which he is the only person talking and woe betide anyone who tries to change the subject, and as he simply repeated the same phrases and ideas over and over, there was no point zoning in.
It does make me sad when every little 'game' I play with ds2 has to be immediately shot down in flames, we can't just run with the idea
("No, Ds1, we know trolls aren't real, we're pretending. Because it's fun. Well your brother does think it's fun. No, I know you don't. No, we aren't going to stop doing it. Ds1, he already knows, gaaahhhhh ds2 tell Ds1 you know that trolls aren't real, thankyou, now, Ds1, we are going to go Bang Bang Bang over the bridge again, you don't have to but we are. Just don't listen if you don't like it. For God's sake child, he already knows ggaaaaaaahhhhhh Darling. he's not frightened of the troll that isn't even there, yes I know it's not there too. He's playing. He thinks it's fun. Right, I am not talking about this any more. The end. The END, I said. Let's go and see if the kiosk are selling ice cream yet.")
