I have been just breastfeeding for almost 3 weeks and Colton has went from 7 pounds 4 ounces at birth to 8 pounds 2 ounces today! If I could stay home his first year and just breast feed I would but in 3 more weeks ill be headed back to work and both formula and breast will be what he eats. My baby boy is growing out of his newborn clothes and we are about to finish up all the newborn diapers and move right into the size 1 diapers. Ugh my little baby is growing and it's making me sad!
