She is actually great. Thankfully I'm still in baby mode, so it hasn't been a real struggle dealing with another baby (we have 4. Ages 7months, 2, 6 & 7.) It also helps that she is rarely left alone and I won't lie, the first couple weeks she slept with us until she adjusted to the crate at night.
I would say 4 weeks old I saw your other post with your son and just had to look at your profile as she looked way too young I am glad you are aware of her real age too bad she was not able to stay with mom longer I am sure she will be a great pup enjoy her she is beautiful.
Very very cute! Shame on the breeder for lying about her age. The next time you get a new pup, keep in mind that 6 weeks (the age you thought she was) is actually too young as well. Pups may be eating solid food at that age, but they really need to stay with mom and the litter until 8 weeks, for mental development.
