Dogs behavior deteriorating

We have 2 dogs, and we love them both. One we got as a puppy almost 3 years ago when we got married, and they other we adopted 1 1/2 years ago. She had been running around through farm fields, and was taken to a shelter where she sat for almost a year without being claimed. Our first dog was mostly good (a little naughty with the garbage or chasing a cat here and there) but nothing crazy. The other dog was also pretty good, but we learned she did have some food aggression issues. Both had been good with our toddler until fairly recently, they’ve both been growling and nipping at him. We are trying so hard to teach him how to pet them nice, and not take things from them, but it’s hard because damn he is quick! I’m a week away from having our second child, and the dogs are getting naughtier. They’ve broken out of our yard, and so my husband made a kennel area for them, and they dug out of it. 🤦🏻‍♀️ One has started eating shoes and socks, and the other has begun pottying in the house. I’m feeling so overwhelmed. One day when they escaped our yard we almost saw one of them get hit by a car, and it made me sick to my stomach. We live by a few busy streets, and leashing them in the yard makes me nervous because I know of 3 animals who got strangled with leashes. I don’t know what to do. I love them both but I can’t handle the constant stress they’re putting on me, and I’m so worried about them biting my son or our new baby. I’m NOT the person to get rid of a pet, but I’m just feeling lost. I love my dogs, and love to feel protected when I’m home alone. To answer questions: yes they are both spayed! And they do love toys, however one of them gets far too aggressive with toys, so they can’t play with toys together, it has to be individually! And I could see that maybe they do need some more exercise, and will definitely try that.
