I used to feel the cold sooo much, constantly wearing layers and whinging at DP to turn on heating. I have a picture of me making Christmas dinner the year before DD1 was born and I'm wearing a wool hat and down gilet in the kitchen!!
I basically got the pregnancy heat with DD1 and never lost it (she's now 2.3 yrs old).
It's amazing...I was walking round today in jeans and t shirt, I'm wearing a nightie to bed instead of 2 pairs of pyjamas.
Is this a recognised biological post-children THING or am I weird though very happy that my internal thermostat has revved up
