So DS took some milk from a NUK bottle today but then seemed to throw most of it up

[PenguinArmy]

DH gave it to him straight from the fridge so I was thinking maybe it was due it being cold. However he has taken 0.5-1oz from a doidy cup before and not thrown it up. He took 1.5oz and later 1oz and was sick both times.

Any ideas?

He is 6 months and I want to leave him for a day next week.

Did he need winding afterwards? He will take in more air through the bottle than from a cup.

I wasn't there, but will suggest to DH to wind him every few minutes.
