Ttc and working with children

Courtney
I am a nanny for 2 families, 3 and 6yr old boys and 4yr old girl and 7yr old boy. I've done it for 3 and half years, the little girl was only 7months when I started so feels like my own. Where I'm always going to play groups and have a little nanny network I seem to always be about pregnant women, women with babies, even at drop off and pick up at school can't help but feel a bit sorry for myself as nearly everyone there has got 1 child or more! It gets me down a little bit. I've been ttc for abit 14months and sometimes feel like it's never going to happen for me.
Can anyone relate?
