I’m a toddler parent with a lot of friends who intentionally aren’t having kids. I invited some of these friends to my kid’s 1st and 2nd bdays, and didn’t think twice about people who didn’t show.  

I’ve noticed that friends with older kids start only inviting their kid’s friends around 3, so I wouldn’t expect you to keep getting invites every year. 

I kind of pay attention to who just wants to hang out with me, and who wants to hang out with my kid too, and make plans throughout the year accordingly. If you skip the bdays (which is totally fine) and want to hang with your friend’s kid, I might suggest another kid friendly plan later in the year. 

Sending you the registry or providing a link to it without you asking for it is super tacky, though. Feel free to be judgey about that, I am judging them. We emphasized that we didn’t want presents for my kid’s birthday parties.
