I'm the opposite with the ages. I would prefer they come to me young (11-12 months). They learn my rules and what works and doesn't work with me. Once they hit almost 2 I find it such a struggle to get them to 'unlearn' that whining works at home but not here, or that their parents will answer them when they grunt and I won't unless they use words. I like to train them young lol

I personally, would give her the rest of today to get back to you if your 100% sure that this is the child who would fit best. I think we've all been through this where we wait for who we think is perfect and lose out on the 2nd choice...or we cave and take the second choice an hour before our first choice messages us back...you just never know in this job.
