Replacement screen for Lexibook Childrens First Tablet

[cally1910]

Hi, I hope someone can help me. My kid dropped his Lexibook My First Tablet and has smashed the screen. I have replaced a couple of android tablet before but am struggling to get hold of a replacement screen. It has android 2.1 os and the screen is a 7" (17.8cm) with gravity sensor screen. Screen resolution is 800 x 400. Any help would be much appreciated. Thank you.
