Welcome!
Computers are vert intresting to babies
There are a few options to try. Firstly have you considered hooking the computer up to your TV and watching LM on the super sized screen? It's not difficult to do and makes math very interesting.
You could also throw a sheet over everything but the computer screen and see if that works.
Or maybe a portable laptop if you have one?
Also there is a Doman dot math app you could try on the iPad for the days she just won't sit and watch. It wouldn't hurt to do both programs each day either! Especially since she likes the iPad.
There is a. Way to run your computer from your iPad also. You need to download splash top on both devises and have a wifi system. But it will effectively be little math on the iPad.
Search splash top in the search field up the top for instructions.
