Birth weights with a different partner

[Number3cometome]

Hi all, bit of a random one.
My first DC was 9lb (born on due date) DC2 was 8lb 2oz at 38 weeks.

Just a bit of research / fun really - but how many of you other ladies have had a big variation in birth weight when with a new partner?

I am 11+4 with DC3, new partner.

Interested to see how the birth weight theory works!

My first was 6.6lb ... my second (with new partner) was 7.2lb

Interesting - pretty similar weights. Any idea how much you were at birth? I was 8lb exactly
