You have had the kitten only 2 days now. Give it time to settle in, and used to a routine. Its missing its mother, but this will soon pass. just give it lots of cuddles. Toys are a great thng for kitten to play with as well. the best toy and cost really nowt, is piece of newspaper rolled up into a ball, it will ,love the noise and chasing it. It will also help as Kittens what we think are playing, are really learning how to hunt ect. Give it a couple of weeks and it will soon settle down into a routine. Sof toy may help for cuddling up to. Time is the key here.
