My hair is almost always in a sock bun, and the few times I had my hair down, DD burst into crying. I didn't make the connection the first couple times, thought she was upset about something else. But I'm noticing this is getting more obvious. Like she'll stare at me for a while as I smile and talk to her normally, then a very sad crying. She doesn't have separation anxiety at all, she's totally fine at daycare and when my parents watch her sometimes. This is getting me worried as I have an appointment coming up for a makeover! I had planned on getting bangs cut and dying my hair completely different color (a subdued version of cherry coke). Now I'm not so sure. Never experienced this with my DS.
If your LO reacted to you changing hairstyle, how long did it take for her/him to get used to it? Right now, my DD basically cries and acts sad until I pull my hair back in a sock bun.
