Hi girls!
My DH sounds similar to yours. He talks to my tummy a lot, asks how my little eggies are today and chats to the baby.
He thinks I'm in a perpetual state of being 'knocked up' so chats to the baby a lot, even pre-O, during AF, anytime. He's convinced I just don't know Im pregnant yet. It is soooo sweet and a really positive influence.

He has only just started to take an interest in my temping/CM stuff beacuse before he wanted it to be a bit of a surprise and we were both a bit surprised it didn't happen first time (like they threaten you with at high-school)

I guess I feel like Im letting him down if I get sad when AF arrives. He's just in a constant state of clucky excitement over the next cycle or the next one or the next one. It's just lovely
