I am experiencing exactly the same thing you are going throught except my children have just stepped into their teenage year. I really miss when they were young where we would spent time doing things together. Really value those moments and now memories.
Omg… as a mom i can definitely relate to this. Tho my big boy is only 4. Whenever i imagine that one day he will no longer need me as much as i do, my heart sinks a little bit🥲
