Colds with 2 month old

Tanisha

My little girl is turning 2 months this Thursday and I’ve noticed today she’s barely wanting to finish her drinks. Whenever she’s being fed too she’s bringing up some and then isn’t on others, she’s also crying during feedings. I seen too she’s not getting all her burps up so I don’t know if it’s colic or not?

Her poos have changed colour too but nothing alarming, she’s also wanting to sleep more. My eldest has a cold as well atm but that started recently too. So could it be a cold or colic?
