DD has always been really easy going around adults and strangers. She won't hold her arms up for them to pick her up or anything but she won't cry either. I was happy with that and felt somewhat relieved that I wouldn't have to worry about stranger anxiety (at least for now).
But at her party yesterday there were about 30 adults and 10 kids and she was passed around the crowd the entire time. Not.one.squeak. She was as happy as can be with all of those people. I hardly got to hold her but that's not a big deal (apparently for her either lol) because I was playing hostess and whatnot. And we don't live close to family so even the grandmothers are pretty much strangers to her. At one point DH's best friend takes Alaina and runs around the park with her and so she's pretty much away from the tent and all the happenings. I figured she'd look around and be like where's my mom and dad or something but NOPE, just enjoyed the bouncey run around the park with this guy!!
Anyone else's DC like this?
Re: Is your DC alarmingly NOT anxious around strangers?
DD is like that for the most part. She's very social and warms up to people quickly.
But, every once in a while she runs into someone that she decides she doesn't care for and all hell breaks loose. All she has to do is see one of my aunts and she bursts into tears.
Yup, just this past Friday
Forgive me, but will you please remind me how we internet-know each other?? I want to say we were doing Ferber at the same-ish time in the past but I'm not 100% on that!!! 
I've been around plenty of kids like this. I don't happen to have one (usually cries when DH picks him up if I'm also in the room
), but I've met so many babies and toddlers that are happy as clams to be passed around.
She's just a social gal.
When my oldest was a baby he was just like that. He could not have cared who was carrying him around.
My youngest doesn't like strangers to hold him though. He'll smile at them and stuff but doesn't like them trying to touch him.
Heehee, is it bad I tend to think it's her just being happy she's not staring at my mug again?? lol
Yes. I could have written this myself about DD's out of town 1st bday party.
She was even running around at the airport, smiling at strangers and trying to touch their legs, arms etc.
She is around two different caretakers (not relatives) on a daily basis and she's always been very social and easy going (like her parents)
This is almost Oliver exactly. He loves EVERYONE ...except my brother's fiance. ...and she is baby-crazy and loves him to pieces so it hurts her feelings. I consider it my own personal karma for her making me wear this freakin hideous bm dress in her wedding.
My DD is like that. She will go to almost anyone. Just like you said she might not reach for them, but she won't be bothered if someone she doesn't really know scoops her up. She hardly looks for us when she sitting with someone else even if she doesn't remember them or see them often.
We took her to the park over the weekend and I ended up following her around while she said "hi!" to virtually every stranger and child in a 30 foot radius. It makes me very nervous that she is so overly friendly and not cautious of strangers. I'm going to have to teach her very well when she is old enough to understand. I can't even think about her not screaming for help if a stranger were to grab her....
