LO is 2 mths old today. Realised nowadays when he wakes up he doesn’t cry immediately for milk. My baby awake window time is 1h..nowadays when he is awake he will look around for awhile. This eats into his awake window time and we don’t know when bb is hungry. Bu the time he cries for milk and we prepare , feed and burp him midway he is sleepy already and often doesn’t finish his 100 ml. Is this common?
