Thanks for adding to the conversation. Absolutely it can be the other way round.
You make a valuable addition to this discussion, thank you.
What I would say is that life before children is very different to living life as a childless person who suffers every day with feelings of grief and exclusion and invisibility , they may be enduring crippling rounds of IVF and surrounded by friends getting pregnant etc.
Similarly life before children is also different to living intentionally childfree. This sector experience stigma and ostracising, often being ousted from friend groups.
It's just different experiences, no one group can truly understand the other as they haven't walked in their shoes, and that's ok. All we can do is be compassionate and try not to compare and celebrate each other for all that we are. :-)
