Since a week, my almost 4 month old baby is not sleeping as he used to do earlier. At night he was sleeping well at night waking up just twice. But since a week he is having disturbed sleep and keeping waking up every hour which is 5-6 times. To see if it's because of milk not being enough, yesterday night we fed him in the bottle as he took it as much as be could. Kindly let me know if any thing needs to be done from us to rectify this. Even during morning times he does not sleep well. Overall his sleep in day will just be 8 hour and which is not a proper peacefully sleep
