Husband changes his mind about TTC

Lauren • Welcomed out first baby on September 18, 2017!
I'm about to turn 31, and a three months ago my husband and I decided we wanted to start trying for our first baby.  April and May didn't pan out, which was disappointing but something I was prepared for.
Yesterday, however, he lost his temper at our dogs.  They're always a bit wild when we get them ready for walks, especially our German Shepherd.  We've only had her for a couple of months so she isn't as well trained as our lab mix.  Anyway, he got really frustrated with them.  I went to check on him and he told me that his temper with the dogs is a sign that he's clearly not ready to be a father.
I reminded him that no matter how many years pass or how much practice he gets, there will always be times when he loses his temper (and when I will lose my temper as well), and that wouldn't make us bad parents.  I reminded him that dogs are not children and can't understand us the way our kids would eventually be able to.  I tried to do this very gently.
The thing is, we've been married for two years now.  There's still time to have a baby, but he's always wanted three kids and I've always wanted two.  I want to give him plenty of time to feel ready but I also know no one ever really feels ready, and I don't want to wait until my late 30s to *start* our family.
I would never try to force him but I'm feeling pretty let down and discouraged.  Plus my parents have put a decent amount of pressure on me.  My brother passed away so I'm the only one who can give them grandchildren, and I know my mom is especially aware of my biological clock...
Anyway, sorry for the ramble.  I don't have many friends (I just moved overseas for hubby's work) and I needed to get this all off of my chest.
Good luck and baby dust to all you ladies! ✨✨✨. Thank you for reading!
