Help Me Understand?

My husband and I had our first kid 4 m ago. His best friend had their children (twins) 3 month ago. Everytime they talk about their troubles with feeding, diaper rash, sleeping, etc. my husband or I will respond with, "oh yeah we know how you feel. We're right there with you." Or "when our lo did that, we did this and it seemed to help." I know they are a month apart and we try to give helpful advice. Being first time parents. We are all figuring it out along the way. However their response is always "we have two. You don't understand. Or "whatever you're going through is 10x worse for us because we have two babies. You guys only have to worry about one." Etc. I could go on and on. One day I mentioned how tired I was because I breastfeed and still wake up every 2-3 hrs to nurse my little one. And his friends wife had the nerve to say there's no way I should be tired because once again, I don't have 2 kids. Which by the way they are formula fed. So their dad can help feed them. They switch off every other night 🙄 They always discount the fact we are both first time parents. They emphasize that they have 2 babies all the time. It's actually starting to get to the point my husband and I don't want to hang out with them. How do we fix this friendship?
