Duyan

When my baby was 6 months old then, he used to sleep on his baby hammock and if he's already in a deep sleep, we'll get him in the bed and he can sleep well until morning but when he turned 9 months until now that he's 14 months, he can't sleep in bed anymore. He just want his duyan. ☹ Gusto ko katabi namin siya mag.sleep na sa bed. What should I do?
