Yes, this is why I don't know many people with babies my son's age. I have my friends from when dd was a baby and of course IRL (as opposed to parent-life) but I get tired of the assumptions that this is all interesting conversation. At such times I often feel desperate that I'm wasting my time...when dd was small I played with *her* in the playground and ended up being the Pied Piper rather than die of boredom talking to the parents. Fortunately now I have enough friends (though not with babies

) with whom I can be relaxed and talk about politics and so forth as *well* as kid-related stuff, which IMO is only interesting when infused with one's beliefs about everything else.
Years ago I thought I would never homeschool here in FL because the women I knew who did it spent all their time (so it seemed) chauffeuring their kids to/from classes and activities that weren't long enough to leave them at so they spent their days chatting...ugh. I can talk the hind leg off a donkey but as the OP said I like acknowledgement of, and the chance to show off, my brain. So even though I'm home with the baby (and homeschooling!) I often still describe myself as a doula

: or a former Waldorf teacher

: for a few reasons. People *do* treat me with greater respect, and perhaps I treat myself with greater respect by the description; it then follows that conversations have more to them than preschool and toilet training and how to cut a mango so your toddler will eat it.
