3 things to look out for: 1️⃣ Weight gain: if the child is gaining weight by 300 to 400gm in 2 weeks 2️⃣ Urine frequency: daily you can check for urine frequency, if it is above 8 times in 24 hours 3️⃣ Child is active and not irritable or lethargic If none of the issues are there, then need not to worry. It is okay if the child misses one feed and is normal otherwise.

What I suggest for parents and grandparents is 'shared responsibility ', a term coined by me, jokes apart, I mean to say, you try to stay awake in the first half of the night, then express your breast milk in a sterilized container and feed the baby with the help of another caregiver in the second part of the night. This would reduce your tiredness.
