Teething?

Klaudia

Hey! My LO is 4 months and eating lately has been really difficult. We combo feed, but i'm the last 2 weeks, sometimes he refuses the boob, sometimes does not want a bottle, does not want formula, wants breastmilk... Every feeding is different. I dread his feeding and feeling totally defeated... I think he is not eating enough, so I am worried. He is fussy and putting his fist in his mouth a lot. Is he teething? Is this feeding thing normal?
