3 month old feeding less

[lockdownpregnancy]

Hi everyone!
My DS is 3 months old on Tuesday and whilst he is a brilliant sleeper in the evening during the day he is a little tinker. I've posted before about it and still an ongoing battle!
However! We are now falling into a pattern of not feeding as much.
Normally he would have 6oz every 3 hours and he's been drinking that for the last month or so. He finishes every bottle so we increased his feed to 7oz and he wasn't drinking it all so went back down to 6.
This past week he isn't finishing any 6oz bottle we give him. He has anything from 3-4oz's.
He is a big baby which is why we increased his feed and up until this week has been feeding brilliantly.
Any one have any reason why now, all of sudden he just doesn't finish any of his bottles and the amount he is feeding has dropped? Is this normal, or should we be worried?

Their growth slows down at that age, but they aren’t using more calories for mobility yet. Totally normal that they take a little less at feeds. They also sometimes start to poo a bit less because they are more efficient at using what they are taking in - again, this can mean they need a little less milk.

If you’re still getting plenty of wet nappies with clear/very pale urine and your baby gains weight in line with growth charts, then you have nothing to worry about

Thank you @crazychemist most reassuring 🥰🥰👍🏻👍🏻
