I agree with all the above advice and just wanted to let you know that at 36 weeks they did an ultrasound and put him in the 90th percentile, said he weighed 3.7kg and had a very large head! Went on to have all my fundal measurements normal and midwives said theres not a big baby in there! Then went on to have a 40 minute drug free labour paranoid about pushing out a big baby!
So 5 weeks later he arrived and weighed 3.77kg which is what they said he weighed at 36 weeks!
Scans def are not accurate enough for me when it comes to weight and size!!
