hey that was really touching. A few grammatical things to make it flow a bit smoother...
"Hair -- so soft! -- that curls up tight"
the reason I suggest that change is because I think the meaning of the line is twofold:
1. "hair that curls up tight"
and
2. "the hair is so soft"
"but since we are nothing but babies ourselves we will wait til the time is right!
"
I say you make that into two lines and make a few contractions:
"but since we are nothing but babies ourselves
we'll wait 'til the time is right!"
like so.
