Any laptop is good actually. If u feel its necessary though, i guess u could put parental controls on it but i got my 1st phone when i was 6 & 1st laptop when I was 8 with no restrictions. Just make sure its clear 2 them that if anything they dont know about pops up that they need 2 c u about it. i recommend dell, many computers these days r around 200-300 $. Check out the dell website
What? She seriously needs a computer, at 8, to do her homework? I have never heard of this before and I have 4 kids! 2 are slightly older and school age! Take your child to your public library and use their computers.
