It's so hard to tell. Jake seemed to take forever to get to 3 lbs. and he stayed that weight until just before he turned a year old. Then, he had a growth spurt and ended up 4 1/2 lbs. Jackson is 9 1/2 mos. and is 6 1/2 lbs. and has seemed to stop growing. He may have a growing spurt, he may not. As much as I like Jake's tiny size, I honestly prefer Jackson's bigger size. I worry less about him, but we have to be extra careful around Jake.
They say to take their 8 week weight and triple it, or their 12 week weight and double it. But, that is not always accurate. |
