I honestly think that no matter how much time you spent with your daughter (even if you were with her for every second of every day) you'd still feel the way you feel now, like you mightve taken the time for granted. But you'll still see her everyday (if not for a short time), weekends, and holidays/breaks (the next six weeks will FLY, leading you up to that week break). I'm not a parent but I'm sure in time (in weeks, I'd imagine) you'll find that you can cope not seeing her as much, and you'll just cherish those times you do spend with her even more. It's fantastic she's excited for it, kids can struggle with going to school for years, you can rest assured she'll be enjoying herself
