My 4 months plus baby suddenly become fuzzy before sleep. He used to drink his milk and dose off. But now, he keep opening his eyes even he is sleepy and cry. Is harder to smooth him to sleep even nap times. Diaper and food all done. And even he fall asleep he will suddenly cry like as if having a very bad nightmare that kind of cry. Any mummies encounter this? May I know how much milk does a 4 months plus baby drinking? I giving him 90 to 120ml. He is currently 7kg plus. I hope is normal...
