My little guy was on the 25th centile at 20 weeks. Today 29+1 he jumped to the 80th centile weighting approximately 1.565kg (3lbs7oz)!! I am schedule to do a GD testing, but meanwhile I wonder should I start watching what I eat? I am up 9kg from my pre-pregnancy weight which I believe is within the normal range. And, should I expect a 10lbs baby at birth? This is my 2nd pregnancy. My first was born on the 75th centile, but we didn't experienced this big growth in such a short interval, this is why I'm a bit concerned. TIA, xx
