3 Week Old Kitten Not Eating Much

[New kitten owner]

I took in a 3 week old kitten recently. She was eating out of her bowl right away & gaining weight. She’s about 6 weeks old now. Three days ago she just seems to have lost her appetite. She’s still very playful & seems fine, she just won’t eat much. She’ll nibble at her food & then loses interest. I hold her & play with her every day. Should I be worried?

With kittens this young i always worry. They are so fragile at this age. If she is not eating well i would have a vet check for the baby!
