Only two of my close friends have DC. Two of DH's friends have LO. DH is three years younger than me, which means that I'm asking him to do something I wouldn't have been prepared to do at his age.
Just exactly as you found, CuppaTee, once sufficient of DH's friends had got married, DH was happy to do so as well. I think this will be the same. So I keep desperately hoping DH's friends' wives will make announcements, but I think they're probably thinking the same about me!
He's just fed up with hearing about it. I've no idea how much I mention it but from my (perhaps slightly paranoid) point of view it seems constantly. I'm almost constantly thinking about it and restraining myself from mentioning it! DH is willing to talk about it a bit, but doesn't really see what the purpose of the conversations are. Poor DHs - what they have to go through!
Leptin you say that finances are one of the reasons for waiting. What are the others? I have such a combination! Finances, DH, no house, fear, work... I'm planning to save £5k before I have the baby, but most of that is to cover loan repayments while I'm off work. The main costs are going to be childcare, which I'm expecting will cost £800 to £1000 a month. But DH has started making noncommital grunting noises which, if you listen carefully, sound like "why don't you stay at home with the baby for longer?" But that must be my imagination.
