R.D.
HAHA!! It's a phase, enjoy it while it lasts :)
My middle child used to be afraid to put her feet in grass or sand. I could literally sit her on a 2x2 foot baby blanket in the middle of the beach or a field, and she wouldn't attempt to leave the safety of the blanket!! It was better than hauling the pack and play everywhere!
Enjoy it while it lasts, this time next year, your kiddo will be aiming for puddles ;)
