at what age is typical for reguritating?

[Sweet Louise]

Louise is 15 months and loves loves loves my best friend. Today, she kept trying to regurgitate for her. My friend redirected her but she was clearly trying and clearly succeeded. Is 15 mos a little young for this behavior?
any thoughts appreciated.
thank you.

No, it's not too young. Many baby birds will regurgitate to show affection.
