9 month old feeding all night on strike in day

[Onemorecrisp]

9 month old takes no milk during the day, eats three small meals fine.

Wants to feed every 2 hours at night, if he is not fed on waking and I put back in cot screams louder, have got 2 other children sleeping next door so cannot leave to scream.

Help!!!!

Have tried adding milk to foods in day to “fill him up” makes no difference at all.

Gosh I could have written this, my dd is 9 months on Sunday and sleeps 7pm until 1/2am fine and then wants milk every 2hrs which she never did before. Is this a thing??
