I am wondering if anyone noticed a growth spurt around 4.5-5 week mark? My daughter went from sleeping well in the night, which included 2 or max 3 feeding with one 5 hour sleep stretch to wanting to nurse every hour all day long and waking up every 35-45 min, wanting to be held or passing something. She is also extremely cranky even when I am breast feeding which at least in the past used to calm her down. Her weight and height gain are in-Line with what is expected so I am not sure if it is a latching or let down issue. This has been going on for last 3-4 days with varying level of intensity. I feel very let down like I am failing as a mother. Any insight on the issue would be greatly helpful.
