My baby he don't drink full fat milk from last 15 days he has his dinner at 7:30 then at 9:30 I try to give him milk he don't want to have what to do

I mix with rice and homemade cerelac dal mix dal cook and give in the afternoon sometimes at night

Taheseen mabbe he
is still full with dinner . U cab mabbe try giving flavoured milk which is exciting for them . Or also get fancy straws or a new cup which would make him wanna drink milk .
