Brought my LO for baby spa, she was really cranky at night. Is she too excited from it?

Cranky can be due to many reasons. It could be tired, hungry, overly stimulated etc. Check on child's schedule, you can find the reasons for her crankiness. If u think that it is due to baby spa, then prepare her b4 hand that she is gg for her swim etc. Babies are smart creatures.
