I only have one grand, but it was the same with him, when he was little.
When my first grandbabies came along I was ecstatic, nothing like it :)
I worked 50+ hrs/wk then, took vacation time with them etc. You’d think it might get old but it doesn’t. Just work at home now, partly disabled, every grandkid is just as special and now I have more time to love them in person :)
Just for clarity, 6 of those kids are adopted. Four of those were already old enough to be in school but all are just as precious.
