18 month old won’t let me put him down for nap or bed.

For the past two weeks I have not been able to put our son down for a nap/bed. We have a great route. That has not changed. We normally take him to his room feed him a bottle or I nurse him. Then we put him to bed. He is always awake when we put him to sleep and generally rolls around for a while before going to bed. My supply has gone down but I have been topping him off with a bottle for months. He will go down for my husband with little or no issue.

Any ideas or mommas experience this?
