I really like it - it’s warm and comforting while also being tailored and a little aloof at the same time. 
Only downside where I am (a nn obsessed country) is lack of obvious shortenings. I would try to enforce full name were it my child - but I guess you could go Aute, Auttie, Audy/Odie, [name_m]Tommy[/name_m] or maybe [name_f]Amy[/name_f] though that’s taking it to a new name.
