Are these signs he will be proposing soon?

We’ve been together 7 years and have lived together for almost 2. Before moving in together, I told him I wanted to eventually get married and gave him my timeline and he told me I didn’t have to wait long. Last year, a ton of our family members seem to have been getting engaged from my cousin, my sister, his sister, his aunt, etc. That led to all the weddings being this year, so it’s been chaotic. Not to mention his grandparents both passed away this year.

Despite his grandma passing in October, he’s been talking a lot more about marriage and kids and I think maybe signs of proposing? I’m not sure, what do you think?

1. He randomly told me that he wanted a diaper party when we have a kid.
2. During discussion of weddings and rings among our married friends, he would bring up what type of wedding we both wanted and then asked how to find a ring size.
3. He asked me if I wanted to marry him still.
4. He usually doesn’t acknowledge diamond ring commercials but it was on the other day and he was jokingly asking if I wanted diamonds.
5. He pointed out these cute baby clothes section in a magazine and showed me. Jokingly saying we should get it right now for the future to use.
6. He asked me if I was still ready for kids by the age I gave him a couple years ago.

I was thinking of bringing it up again in conversation to confirm my expectation that we will be engaged in the next few months instead of wondering and waiting. We have the holiday, a huge family vacation coming up, our birthdays, so I feel like if he were to do it, he’s waiting for that moment because he’s that type.
