Baby Needs To Be Carried Around House While Drinking

My 11 weeks old baby is very fidgety, esp at night. I can see that he is hungry for milk but after he drinks for like 3 mins he rejected the bottle. I tried again, he takes the bottle and then rejects it. Tried to burp but he does not want to sit still. He will then become very fidgety and needs to be carried and walked around the house in order to drink his milk! What's wrong 😟
