To me it seems she is delightful all the time - at least judged by what you post on Instagram. Or maybe those are the only moments you find worth showing?
Delightful or not may also be part of a process of getting used to other people than the parents to look after her I guess.
Ha, instagram surely shows the better moments. But, actually, she feels like a completely different baby now than when she was under 2 months. I'm pretty sure we're at the best age now. She is happy and fun to play with, but has started playing on her own as well. She still naps for long periods of time (currently she is outside on the back porch happily sleeping), and we can just load her into the stroller/car seat/ ergo carrier whenever we want her to go somewhere. She wakes about every 2.5 hours at night (we were doing better in the US before we came back and jet lag hit), but she feeds quickly and then sleeps. I think I got about 8 hours of sleep last night (though broken up). Anyway, this is all to say that she was not so delightful in the beginning, but now she is pretty great :)
Ha! the first time was a bit different, huh! I guess she's growing up;-) So glad that things are easier than in the beginning. Yupee!
Ha, rereading this just a day later.... and she was a horrible sleeper last night! Just goes to show that every day is a new and exciting challenge!
