I have a 6-month old. Here is the most important advice you will receive for the first 3 months of your baby's life. A) learn how to swaddle tightly. If possible swipe the linen swaddling blanket from the hospital. The linen texture grabs better than felt which most other blankets are made of. Also the size is a little larger. Again, it is all about tight tight tight. Your baby has been cramped for many months. Being loose feels awkward. B) Mylicon (gas drops) are your salvation. The instructions say to use as needed up to 12 times a day. Trust me. Your baby needs them before feeding EVERY TIME for the first 2 weeks. Then you should be good to go. This advice took a non-stop crying baby and turned him into a sleeping through the night (except for feedings) baby instanly.
