I had a message from Léa's breeder waiting for me when I got up this morning.
Léa is currently down to 2 feedings a day and is eating less and less of the formula and is now eating much more on her own and is eating pretty much every type of food offered to her that is not formula. Her weight is now around 315g. She's really big on playing, which she apparently finds much more interesting than flying nowadays.
Here are some of the pictures that were sent in the email.
