Dont worry, your baby is simply growing up
I have a 4 month old that currently looks like an old woman needing to dye her roots or one of the Hyenas from The Lion King movie~!~~ no kidding she is a pitiful sight right now...my male remained black on his back and only went thru this ugly stage on his head so we are really looking at her as the ugly duckling right now.
Your beautiful swan will evolve right before your eyes...promise!
