New AG owner

I’ve gotten a AG and it’s around the age of 6 months I believe. The weaning isn’t fully done yet, I feed it nutri cerelac and it eats fruits on its own. But it isn’t able to hold the fruit or seeds with its hand like my other parrots. Is it normal because it’s young? Any other advices? Can I give it a shower spray or advices in general for a new AG.

Thank you
