I have a son who will be 3 in April who currently weighs 40lbs is 38" tall. We are expecting our second child to arrive late in July. I have a Chicco Infant carrier from my son which I want to reuse. I am looking for a double stroller for when baby #2 arrives. I think I want a side by side as most of my friends don't like front and back. I am little concerned about a sit and stand as I think there will be times I need to secure my 3 year old. Any ideas would be great. Thank you.
