13 week old refusing milk

[Willow4987]

Hoping for some advice or to hear from anyone who’s experienced the same

My 13 week old DS has suddenly started refusing his feeds

He’s been on a roughly 6oz at every feed, taking roughly 38-40oz a day and has been this way for a couple of weeks.

He’s been weighed last week and slightly slipped of his percentile but he’s so big they aren’t worried and he was having the correct amount of milk a day

But on Friday he suddenly started refusing his milk, taking 3oz and then screaming until we stopped

So then I tried a few things:

Took him off the size 2 teats he was on in case he wasn’t ready
Stopped his gaviscon (for reflux) in case he was constipated
Checked he doesn’t have a temperature which he doesn’t

None of this has worked and he still won’t take enough milk over the entire day - he’s down to about 25-30oz now and I’m worried

Also his milk hasn’t changed so I don’t think it’s that

Is this normal?

Sorry about the length! Didn’t want to miss anything out

Have you checked his mouth for thrush?

From what I can see it looks normal

My 12 week old DS has started doing this. This morning it was awful. He would not eat and started screaming and thrashing until I sat him up. Very abnormal for him. I looked it up and I am pretty sure he has "discovered the world" and is getting super interested and distracted. In the end I went to the bedroom, turned all lights off closed the curtains and eventually he had a massive feed. I think now they are so much more alert there are lots of things to distract them. So try a silent dark environment and see if that helps :)
