No feedings through the night...

Coco

How will I know when my baby can tolerate no feedings from bedtime to morning? He’s 15 weeks; just curious, will he just basically sleep through the night? I obviously don’t want him to go hungry 🤔... he’s been wearing the Merlin’s sleep suit, since 745 pm, had a dream feed at 10 pm and has not woke up since... I woke him at 1 am (to make sure he wasn’t sweaty or cold in the sleep suit, since it’s his first time wearing it) and he didn’t even seem hungry..to my surprise, I lay him down in crib, drowsy and he was able to make himself fall asleep !!😳, didn’t need me to rock him to sleep, like usual..... so if I hadn’t woke him, to check on him or change diaper, it seems he would have never even woke up to feed... ive read that some babies will sleep 8pm-8am..... so if this is the case, and my baby is ready for that, will he just sleep straight through? Or do I need to wake him? Lol just freaks me out to let him go that long without eating! But if it’s doable, I’ll gladly take the sleep!!! Lol!
