Big foot baby! Lol (please don't grow anymore)

Alexandria • TTC for 4+ years. Got BFP on 6/15/2015 and estimated due date is 2/6/2016!
So Tuesday the doctor had concerns and we got to have another ultrasound. All is good! But now I'm scared how big he's going to be 😳 the ultrasound guesstimated him to be at 7lbs 6oz! His head and tummy are above the average at this stage. (I'm 37 weeks). Then his foot measured 3 inches, so now I feel like less of a cry baby when I get that loving kick in the ribs. 😜
