how to feed distracted 7month old

MiKayla

My son will be 7 months old on Nov 23 and for the past week he has not been interested in his formula much at all. he is so distracted! now he's not a small baby what so ever 21lbs and over 27inches long so he's not missing anything weight wise he eats solids 3 times a day but I'm concerned about his vitamin intake we are lucky to even get 20oz max in him per 24hour period he sleeps through the night so there isn't any night feeds to make up for what he didn't take during the day. he has recently cut his first tooth and I hear teething can cause babies to refuse to eat from a bottle but he won't take anything it's a fight he will take 2 oz here 4 oz there when just over a week ago he would.take 8oz first thing in the morning and 6oz every 4 to 5 hours like clockwork and 8oz before bed. I'm just a concerned first time mom
