My baby is 1 month 14 days today and he is fully latching bm. He poops about 3-4 times a day. This 2weeks baby will go through the 6 weeks sleep regression hence the excessive crying. You can read up on 6 weeks regression and hopefully you will feel better. All of us will go through it. I babywear my son alot these days and i find him calmer in the carrier. Maybe you can try that too? Hang in there! You can do it!
For 1 month old, it will usually be about 6 to 10 diapers per day. It depends on your LO. This is just on average generally for baby. Colic happened due to digestion system due to sensitivity in milk formula or breast milk. There are other reason too however, this is very much unexplainable as majority of babies do have colic. It can happend from night time till next morning for hours.
And this too as well
