Sleep baby sleep

For the last couple of days, Anirud is refusing to sleep in his cot. He was alright with the cot until a week back. Since he was not well due the teething issues, we let him sleep in our bed and now he is refusing to sleep in his place. Yesterday, he cried for about an hour to be lifted from the cot and at last we relented. The Health visitor insists that we shouldn't relent, how much ever he cries. We'll see who wins the next round.
