What do you do with your baby during the day?

M
What's a typical day look like for you and your baby? My daughter is 12 weeks old and I'm having a hard time keeping her stimulated during the day. It's too cold where I live to bring her outside and she's getting bored with her play mat and most of her toys already. She loves the tv but I don't think it's good for her to be watching it all the time. Any ideas? 
P.S.- here's my baby isn't she cute 😆
