Congratulations on your new child. They are a Godsend. Every person's child is the most beautiful they have ever seen.
I know exactly what boat you're in now. I have a 3 month old at home now and trust me when I say I need those little frogs. After listening to that little boy cry for a while, there is nothing better than watching the frogs for 5 or 10 minutes.
I have learned in the last 3 months that a person MUST have a "release" whether it be frogs or a motorcycle ride, you've got to release the stress that WILL build up with a child in the house. Jonathan is my second child, I also have a 5 year old and there is nothing better to teach children about nature than frogs. They are great all the way around as a stress releiver and entertainment.
Frogs are a good source for stress releif and thus easily justifiable!
