My oldest child just moved out. I’m so sad

(((hugs))) It's such a bittersweet time. We dropped our oldest DD (now 28yo) off and I cried the whole way home in the car just picturing her sweet little newborn face. It's such a hard change to know what they're doing all the time and seeing them to then know they are off without you doing their own thing. It's great! But it's sad too. And fair warning, one of the hardest days for me was her first birthday after she went to college.It was less than a month after she moved and it was a weekday and because of schedules we weren't going to be able to see her until a week or two (three?) later. I loved that she was having a great birthday with friends and doing fun stuff, but man was it hard on my heart to not be a part of it.
It will get better and easier once you're past the initial adjustment. My DDs are 28 and 24 and I love having this adult relationship with them now. It really is one of the joys of my life.
