It is actually rare to lose a lot in the first few days. They pump you full of Fluid and you are very swollen on the inside. It takes time to heal. The weight will come. As for lifting your son, you should probably give it a good two weeks - your almost there, and then I would start slow and only pick him up when you have to. You don't want to hurt yourself and go back to the beginning. Most of the stitching is on the inside, and that is still very fragile. It needs time to heal. Congratulations on your baby boy and your new life!
