Lucas at birth, 4 days old, 5 weeks old, 3 months old

Lucas was 2.82 kg (6 lbs +) when he was born. Looks like the okay size to be in.

We, being the first time parents, under-fed him during his first week. He lost 18% of his birth weight in the first week, where most babies lost 10% only. He looks like an old man in his bath, with the wrinkles on his forehead.

Then on the end of first month, we must have over-fed him. He ballooned to about 4kg (9 lbs).

By his third month, he lost most of his hair!

Talk about fluctuation, just look at the new-borns!
