Potty training advice

🐷
So my daughter has recently started walking. She is 14 months old and has been walking for a month now. She's still a little wobbly, but not bad. We are expecting our next in April and it would be amazing to have her out of diapers by the time he is born. Does anyone have any tips on how to potty train? She was my first baby so I've never done this before. 
And after it posted, I realize it may be in the wrong section. I'm sorry but I can't change it now for some reason.
