Heya
My little 1 is only 2 weeks old and I was unable to breastfeed unfortunately so he's had to go onto formula
I'm using cow and gate and recently my little 1 has started to feed less he use to have 3oz now he will have 2oz or less and is sick, his sick is very thick like old milk coming up. He's also very restless now and he struggles to bring up a burp.
His nappy is completely fine and regular
Just want to know if it's something he's getting use or should I change the formula?
