Today I took her to school so I could get some stuff to plan for next week. We stayed in the teacher's lounge during lunch. My 4th grade team is laidback and calm, so no big deal. The 5th grade teachers are loud and boisterous and I think she became over-stimulated again, because tonight she was again inconsolable.
It's important to remember that babies DO have immature nervous systems, and therefore need us to shield them from getting over-stimulated or over-tired. We have to look for "cues" that tell us they are getting tired, and then get them to a quiet place where they can rest.
I looked up techniques for soothing a baby that is over-tired. I found a website/book/DVD called "The Happiest Baby on the Block". The dude (Dr. Karp) talks about 5 S's: 1) swaddling (tightly with arms down by their sides), 2) shushing (louder than their crying, or use some kind of white noise), 3) side (lay them on their side or tummy . . . I prefer us being tummy to tummy with her on her side), 4) swinging (or some kind of rhythmic motion), 5) sucking (pacifier, finger, bottle, or breast).
Most of these I tried before reading this out of instinct (or desperation). I'm checking out the DVD and the book from the library, so I'll be writing about that soon. Hopefully though, I can just avoid the whole over-stimulation thing and look for signs that she is getting tired, and skip this whole frantic soothing thing next time.
