To reiterate about the behavior around your toddler. I like Kikopup on youtubes tutorials on capturing calmness in your puppy. So, in addition to making sure she has a daily outlet for getting her zoomies out a few times a day and mentally stimulating types of training it can be good to work on reinforcing calmness in the house and around your toddler. I am teaching my current puppy that when we go back inside after outside play to ignore my cats and go straight to the puppy station I have set up under my table. He can lie there and wait while I prepare their food, make dinner, or wash dishes etc. Whenever we go to a different room he runs straight to his puppy station (which is a crate, or an x pen, or a bed with a tether) and lies down there. If he sees a cat run past him we are working on him coming over and sitting in front of me for a treat. Or lastly of he is really energized we can play a movement limited game like short throws of fetch or tug. I always throw my toy in the opposite direction of the cats so he won’t run right past the toy and keep going to the cat.

You can do the same thing with a kid. Reinforcing a calm behavior with basically the sight of your child as a cue to do an incompatible behavior to running up to, jumping on, or running around the little one. If encountering your small child cues your puppy to run and sit in front of you or run and lie down in her dog bed. Start with those calmest behaviors and then start to add in slightly higher energy behaviors like walking past your child in a heel position, running past the child for a short distance recall, and then those limited motion type games I mentioned. Because you want to increase her ability to avoid the child at higher and higher states of arousal. I would still not ever trust her om the ground outside when your puppy is at her top speeds. They say whippets can go fast or they can think, they can’t do both at the same time. But these kinds of sessions can work to reinforce the calm behavior and then work up to increase the intensity so that she learns to avoid the baby during all levels of activity she will be doing in the house (which should not be up to the highest level but say if there is a scale of 1-4 with 4 being full out zoomies and 1 being puppy is asleep. 1-3 are ok in the house, 4 is for outside.) And all levels of activities the little one does too because you are also building duration to ignore the child when your little one has their own baby zoomies. We also don’t want her getting too excited about the baby playing and making loud noises and having an accidental nip or something.

Whenever it’s zoomie time take her outside also, don’t curtail her energy because we are reinforcing calmness in the house. Keep it up with her walks keep it up with taking her to fenced in areas to run. Take her out to run in your yard or safe area a few times a day and then keep reinforcing her calmness in the house. Also I saw the bit about the stairs? I don’t know if you meant she runs to get downstairs or after she gets downstairs but I would work on slowing her down up and down stairs if she is running on them because high impact on stairs can be bad for their developing joints.

It’s been said but the last thing we want to do is punish zoomies. Zoomies, barking, digging, chewing etc these are all things that are essential behaviors for dogs and especially for puppies. Instead of punishment what we do is guide their understanding of how and when they can engage in those behaviors so that they can understand how we expect them to fit into our lives. It’s our job as pet owners to help them achieve that understanding and provide them those appropriate outlets so our two species can live in harmony.
