Anyone had similar sized bumps at term but big difference in weight of babies?

[Thankyouandgoodnight]

i.e between PG1 and 2, not the same sized bump as a mates!

My bumps for DD1 and DD2 were both simalar and DD1 was 7lbs and all the way through midwife said that DD2 would be around same weight so was a massive shock when she weighed in at 9lb 1.5oz.
