7mo waking for milk

Hi all,

I won't ramble on unless you ask questions for more info and then i will reply!

Basically, i have a 7mo baby boy. He was sleeping through 7pm-6am for a while, but now he's started waking in the night at 12am and 4am for milk (he's formula fed). I try going in a settling him etc but he screams his hungry scream, once he is fed he goes back to sleep.

We've started weaning him since 5months and he has about 150ml milk and a good amount of food before bed too.

Is this just a phase?!

Is this to do with his naps during the day? (Naps about 3 hrs maybe 3.5 in total)

No matter what, he always wants to be sleeping by 7.

Thank youuu :)

P.s i don't mind getting up to feed him, i love seeing his little face! Just wondering if I'm doing the right thing, or creating a habbit!
