Benjamin at 7 Weeks

I think we have finally found a formula that Benjamin does okay with. He still has times of fussiness and gassiness (is that a word??), but they are fewer and less intense. He smiles all the time and is beginning to coo. He eats every 2 1/2 to 3 hours, including at night. He will go 4 hours sometimes at night, and we are longing for the night that he goes longer! Benjamin is also now bald on top! Just this week he lost the little hair he had on top, except for one long patch. He also has full, full cheeks and a double chin.
