my baby boy is 9 months old he won't sleep well at night times he woke up for every half an hour. I tried to breastfeed him but he rejects and it continues the same daily especially night times. what may be the reason and should I be worried?

A. It is developmentally normal to wake up at night at least through the first year and often for quite a while longer. babies and toddlers might wake from hunger, loneliness or any of the reasons like too hot or too cold, having toothache, a bad dream, not properly tired.
