This baby needs to be watched closely for several more weeks, IMO. I am shocked that a breeder would let her go at such a weight, especially to a home with little/no experience with little ones. (I mean no disrespect to you in saying this) Until their blood sugar stabalizes, they need 24 hour access to food and sometimes regular nutrical.
You did the right thing in getting her to someone who can help...both your little guys are sooo cute and I'm sure will be a joy when they're both healthy!
