Heartbreak!

Shelbi • TTC #2. PCOS SUCKSSS!
My son had just started day nursery.
He's 3, he's never really interacted with other children besides family member children and friends kids.
He's always been with me everyday.
I know it's good for him to be with kids his own age and he loves it.
But everytime I take him it upsets me so bad I feel like I'm pushing him off to other people.
I know it's natural and he's not the only child that goes nursery and not th only mum who probably feels like this. It's just so overwhelming my little baby's growing up and I don't like it lol. Will I ever stop feeling upset because he's away from me? X
