Don't know what has happened to my 2 months old boy. He slept from yesterday midnight till now. No intention to wake up. Never cried for milk also. He only woke up when we tried to dream feed him. Any mum encounters this before? He has become very sleepy.

That's good. Babies will let you know if they are hungry. If you are breastfeeding, it is even easier for them to adapt to a normal sleep routine as night breastmilk has night-time components to help them to sleep through the night. Evening breastmilk contains higher tryptophan levels, a sleep-inducing amino acid. It is followed by serotonin, a hormone which regulates moods and sleep cycles. http://www.telegraph.co.uk/news/health/news/6255205/Why-breast-milk-helps-babies-sleep-at-night.html
