I agree with all the other posters to not have anymore contact with her and to document everything that she says/does/emails etc. Sounds to me like she's just looking to threaten you in the hopes that you will fork over more money. If it does go to court, so be it. It will cost her to do so and in the end it sounds to me like you would most likely win. Negligence of a child MUST come before money! You also need a copy of your signed contract! If not now, for future. Sometimes that it is all you have to support your position as most times this will always come down to your word against hers. I hope it all works out for you. Nothing worse than having to deal with all this drama when you were just protecting your little one!
