Oh I know that must have been so scary for both you and Maize! Thank you for sharing your story with us. It is a great example of how fragile these little ones are.
I understand exactly where you are coming from regarding taking extra precaution with a tiny one--SOO different from one, say over 5 lbs or so. It is like walking on eggshells. I know that sometimes at the end of the day you feel just exhausted!
To look at a little one, it blows my mind that the thought of breeding a female could even cross someone's mind.

Seems like to ANYONE it should be painfully obvious just by looking that is is NOT a good idea to chance it!
Hugs to you both!
