It's hard when you feel so strongly about it and your DH doesn't. Maybe it's just too early for him to get his head around it? Your DS2 is still very little, I notice that men don't always cope too well with tiny babies. They seem to take up a lot of your time and they can see that they make you feel tired, emotional, etc. I don't know if your DH feels this way, but that may be why he feels so adamant at the moment?

My DS#2 gave me a hard time for a while and DH didn't want me to go through it all again because it affected our whole family. But once DS2 got older and easier he changed his mind, he saw that it was only for a short time and that the rest of the time it is mostly great .

We talked about it for many months, we wanted to wait until we both felt 100% about having a third. DH would say he is 40% ready at the moment, then it grew to 50%. Eventually he was at 80% sure he wanted another and that was good enough for him LOL!

So maybe just give it some more time, keep talking about the possibility of another bub with him and hopefully over time you will both come to a decision that you feel peaceful about.

Best of luck .
