She was also most insistent I get a GD test (not that I wouldn't have) because having a previous baby weighing over 4kg is a risk factor.
That kind of depends on the baby.
DS1 was 4.64kg, I had a GD test with him and it was negative.
Yes, he was 10lb 4 BUT he has not macrosomic, just a very long baby. If you'd had a large baby that was macrosomic it might be a risk factor, but not just on weight.

ETA: DS2 was 4.62kg, and I idnt have the test, or GD this time either.
