REALLY DUMB question about couree slings

[ConnorTraceptive]

ok please humor a mo and answer my question and then feel free to go away and snigger.

When measuring myself for the sling should I do it now whilst only 5 weeks pregnant and my normal size or should I wait until I've had baby and then measure my inevitable larger frame.

Thing is i want the sling to use right from the start so don't want to order it once baby is arrived.

apologies for my stupidity

They don't take too long to come so even if you waited until you've had the baby then you'd would only have a few days without.

I would email them and ask, they are quite good at changing it if you got the measurements wrong from what I have heard.
Also the FAQ's here say they will extend exchange period if you are pregnant.
