(((hugs))) I did this with mine when my husband was working across the country, though my DS was older (10 months). TBH I did use screen-time, but usually the kidscbc website here in Canada which has educational games etc. The occasional tv show also helped though.
There were a few other things though that worked for a while - a bowl full of soapy water and a straw )to blow bubbles up), painting, a cache of special toys she didn't otherwise get to play with..... DD isn't the type of girl to sit and play quietly for long, so it was a challenge and I had to constantly try new things.
