Hello Doctor, My baby is 14 months old. Yesterday he slept at Midnight 12'o clock and today he woke up at 10:15 AM. Later he slept for 1 hr in noon from 1 to 2 pm. Later we went outside had walk ( Recently he started walking like 10 days). Later he slept for almost 1 hr like from 7 to 8 pm. Then he woke up for milk and then again slept at 1AM (midnight). These days he's not sleeping well. He's playing and walking well. Even though he's not sleeping. Is this common? Please suggest. Thank you.
