Leaving a child out for not being biologically related

[Tigerstripy]

Without delving too far into backgrounds, (very long and stressful to explain) if you requested photo gifts of your grandchildren would you want step children not biologically related to you included?
If your grandchildren had step siblings via marriage for example, or would you only want your biological grandchildren in the photos?
Assuming everyone is close and accepts the stepchildren, buys them xmas and bday gifts, spends time with them etc.
Would you be angered if your child was left out because they wasn’t biologically part of the family?
Trying to gauge social expectations before raising the subject. Thanks.

I would include adopted children. I do not have step children but I have seen too many times couples split and the GPs are never allowed to see the step GC again.

And everyone on MN would say step GCs were being grabby to expect anything.

Lets ask a more relevant question. If OP and her DP had an acrimonious split and the GPs supported their son, would OP still want ger DC to see the GPs? The answer is almost certainly no as parents never see step GPs as real GPs as soon as there are any issues at all.

No I wouldn't include stepchildren, no. Not if they were my parents. Obviously I would if it was for my DH's (if I had one!) parents as my stepchildren would be their Grandchildren

This.
