Work from home tips?

I go back to work next week. I will be in office 2 days and at home 3 days working remotely and taking/making calls from 8:30-5 I bf and can sit at the computer for a bit with baby eating and being content but I am very worried how to actually get any work done. She will be 3 months old. I can put her in bouncer but might only last alone with that for 15-20 min tops and her playmat the same. Any suggestions from mom's who have been in this situation?? She changes so much every day I'm hoping she'll get more and more independent and able to play with toys and eventually use a walker but it seems impossible right now. Worst case me and hubby decided he'll stay home full time with her if i can't hack it but that's less money.
