My little boy is now 9 months, he goes thru days when he is not interested in the breast, and tends to feed more in the night. what should i do to encourage him to sleep throw the night, he used to take the soother now he wont. I have a feeling he is not having enough. he is on solids but goes not eat much either. he is otherwise happy and i am happy with jis milestobes, he crawls and pukks himself up. any advice or tips are welcomed.
