Hmm, I’m not so sure though. My son slept through the night as well, but he will want his milk at night and will drink it with his eyes close. I doubt he will drink more than his usual feeding amount cause their tummy so tiny, there’s only so much they can drink. I think it’s normal that the feeding drop. Cause now they can hold more milk then they used to and takes longer to digest, and feel full longer. My son turning one, he only do 4 feedings at 160ml per day. Usually when it comes to feeding him, I will normally follow his cues. Like I said, mine normally do 4 feedings per day. But at times, if he wants to drink more, I’ll give him more. And if he doesn’t want to finish his milk, then it’s okay. Babies won’t starve themselves. If they’re hungry, they will cry for it.
My son also slept long time during night. but he drank enough milk when he was awake
