My 8.5month old baby girl has turned very restless at night from sometimes now. Even after having a proper night routine of massage n full feed she keeps getting up every hour or half n hour , though not properly awake but still makes cooing sounds n sleeps after being fed for just few seconds.. this goes on so many times during night.. We are unable to get reason behind such behaviour. Is it normal or she's having some issues?  will sleeping less hamper her growth? The frequency of waking up is very high while other kids of her age have started sleeping for longer hours!
