4 month old suddenly drinking less milk

[JenJen84]

My 4mo baby has suddenly started taking less milk.

She's progressively moved up until she's now on 6oz bottles 6 times a day.
In the last 2 days she's stopped taking mist of the 6oz bottles and wont have more than 4oz. Even with a break.

What could be the reason?

She may have been building up to and doing her 4m growth spurt and now she doesn't need the extra. Is she well in herself?

She's recently had jabs.
She's not napping properly and crying over nothing I can tell.
She cries if I even try to feed her, now she won't even take 2ounces.

I think it's completely normal. This happened with DS at 4 mo, he went from having 8oz bottles to just drinking 4oz or 5oz. I was worried, but after talking to other mums at baby groups, he wasn't the only one. I learnt to relax and trust that he knew how much he wanted.

It lasted for around a month and a half, then he got his appetite back.

Thank you. I'm stressing totally. I'll bring her feeds
Down and let her tell me when she wants mOre instead of stressing seeing a half full bottle!
