The Guardians of the Galaxy Vol 3: How old will Groot be?

When we met Groot in The Guardians of the Galaxy, it was a well-built tree and then we found it as a cute baby in Flight 2. How old will it be in the next movie?
Is there anything more adorable than Baby Groot? Honestly we are convinced that not. If the more adult version of the tree with limited vocabulary was also very nice, we spent a lot of the Guardians of the Galaxy Vol 2 imagining how happy we would be to have a baby Groot in our life. All good things have an end and like all living beings, he grows up small! CAUTION SPOILERS – Always there? Ok – In one of the post-generic scenes of the Guardians of the Galaxy Vol 2 we discovered him in his teens and in conflict with Peter Quill about the state of his room … So we ask the question? How old will it be when we find him in The Guardians of the Galaxy Vol 3?
First what you need to know is that the next time we see Groot it will not be in The Guardians, but in Avengers Infinity War . Yes, the Guardians will be there to help the Avengers fight against Thanos and we should find a Groot adulescent, younger than in the first film, but much older than in Flight 2. The Guardians of the Galaxy Flight 3 will be released in phase 4 of the MCU so after 2020 and one can expect to discover a Groot in full power, in the prime of life and certainly older than in the first film . Unless he sacrifices himself again, we will never see Bébé Groot again. Yes, we too are sad!
