Are you guys still close as adults? Do you wish you had more siblings? Do you think you will always be close?

I have two kids right now.. a boy and a girl.. I am thinking we may be done having kids, but I have 3 sisters and I love having so many siblings. We are still extremely close and 3 of us live within 10 mins of each other and hang out all the time. I worry that my kids won’t have that bond if there’s only two of them
