My baby refused to latch on after 2 1/2 months of successful nursing.

Today my 2 1/2 month old baby did not want to latch on after successfully nursing 5 times throughout the day.

She arched her back and screamed. I tried different positions, each breast and the same results.

After much frustration for both of us, my husband gave her a bottle of breast milk which she took without a complaint. I am very upset because I don't want to give in to a bottle every time she exhibits this behavior. I have used breast shields this entire time without any problems.

Please help. Emily
