I'll change him (= I will take his place doing sth)

[angelene001]

I've got a problem.
I would like to express the following thing:
My friend is going to look after my baby for 4 hours. But when I'm back I will change him.
Is this correct?
Can I express it in a different way?
Maybe:
"I will take turn"
"I will take over from him"

I'd be grateful for your help.

Is this correct? No. That sounds like you're going to change the baby's nappy.
Can I express it in a different way?
Maybe:
"I will take turn":cross:
"I will take over from him".:tick:

Also "I will relieve him".
