12 week old feeding issue

[WaterMelonSugar9]

Please help, I’m tired 😂
My 12 week old was feeding so well, 4-5 oz every feel, full feeds with the odd little ones he would have a couple oz then need topping up, but genuinely very good.
Over the last 2 days he is fussing soooo much.
He tends to be having 1-2 oz. 3 if I’m really lucky before he fusses around, and isn’t interested, however I know he’s hungry or due a feed. Through the night he’s def hungry, but waking up having the smallest amount then going back to sleep then he’s awake an hour later!
i don’t know why he’s fussing so much and why all of a sudden he seems to be snacking rather than having a full feel.
he also now seems to dislike warm bottles so I need to wait until it’s cooled right down to room temp before he drinks it!
any advice pleassseeeeee

This is a good thing, your child is at 3 months and can start sleeping all the way throught the night for 6 hours without waking.

Your child is showing signs of limiting food intake over night. If you encourage this and simply hold them or comfort them. They will eventually stop feeding over night and can sleep all the way throught. They will be extremely hungry in the morning and feed as normal.

There will be parent that tell you your abusing your child. Ignore these idiots and talk directly to your doctor. They will definitely tell you weather your child is of the right weight and size to be able to store fat/energy to sleep a whole 12 hours straight. However most normal children by 12 weeks can.
