If the treadmill made you gain weight so would regular walking so that's not the problem and since you saw your doctor and everything checked out ok. I'm inclined to remind you (not trying to be rude) that any over eating healthy foods or not or food we consume and don't take into account causes weight gain, that's more than likely why you gained weight. I would get a referral to a dietician/nutritionist from your doctor or if you can pay for an independent one I would do so, to make sure you understand portion sizes and what you should and potentially should avoid eating depending on any food allergies, dislikes etc. I had the privilege to meet at least with 2 of them in the past and it really helped me, being here can help but sometimes that one on one help in person really makes some of us get it better than trying to figure it out on our own or online. And running around with the children is always great exercise, hoping the best for you just don't give up.
