This might sound ridiculous but i know alot of babies and none do it.
My baby boy always wakes up for his morning bottle and absolutely screams the house down like he's never been fed. He does this every morning and its the ear piercing scream.
Other babies i know give a bit of warning if its shifting for a bit, or moaning before crying but he acts like he's starving.
He also does it through the day, he could be laughing his head off then almost like a switch he goes crazy.
Is he demanding or is this normal? Is it not? He's fine after the bottle and is fine and quiet soon as it touches his lips.
I also don't mind cos i love him it just kills my ears in the morning and i don't like listening to him going crazy when he's waiting for it.
