Rescued a dog and she’s over active

Hey guys. I recently rescued a Labrador Retriever mix and I really like the dog she’s a big goof ball. However, at the shelter she was calm and relaxed and at home she is very hyper and has a jumping problem she tries to jump on me and on my wife even when she’s carrying our baby (ten months) I’ve scolded her 100s of times already and she doesn’t get it even tried to get her to understand with treats when she was calm. I walk her 3-4 times a day for 30-40 minutes but as soon as we get back home she starts trying to run all around again instead of cooling off. Any help? She’s one and a half. I don’t want to return the dog but her energy levels are a bit worrying when I’m at work and my wife is home as she’s always at 100

Yes I have toys for her
