Just wanted to update Mandie's measurements and weight to see the differences. What I discovered is that I obviously measured her neck wrong last time or she lost and inch and a half LOL!
She was (at 7 months):
Weight = 4 lbs 13 oz
Height = 8 1/2"
Length = 12"
Girth = 11"
Neck (void due to user error of a tape measure

)
Mandie is now 8 1/2 months old:
Weight = 5 lbs 3 oz
Height = 9" (front) and 9 1/4" (back)
Length = 12"
Girth = 12"
Neck = 8"
