4 week difference holy cow. is this normal to get this big so fast ??

Yes; expecailly right now from 16 to 18 weeks you baby doubles in size; seems crazy

what about this big in only 9 days @caytlinn14

yup baby is starting to collect fatty tissue at this point thats why :)

I'm 20weeks and I have not grown at all 😰 @kelseyp1992
