My daughter was not even a month old when I started getting worried that she rarely pooped. She would go 1-3 days sometimes without pooping; I found this odd since she was exclusively breastfed.
I talked to my doctor, who gave me a few tips to get her digestive tract moving, but otherwise seemed unconcerned. In an attempt to help her out, I pumped some milk for her and added corn syrup to it in a bottle.
