I know that the reverse is true here - the first to have a baby probably feels the same.
I’m 41, expecting a baby, and feel out of sync. Friends started their families at about 32 and finished them at about 35-36, meaning they are now at the stage of just starting primary school. Nappies and breastfeeding and childbirth have been replaced by school shoes and school runs and so on.
AIBU to feel a bit sad I’m out of sync with everybody?
