Sit N Stand Stroller

Have you received a double stroller sit n stand?
We are expecting our second child this summer and our daughter just turned 2 when he was born. Should we go with one of these strollers? or are you just a regular stroller travel system for baby and stick with our umbrella stroller for our daughter? And every parent to push a stroller.
any experience with this?
Thank you for your help! "

I think it depends on your daughter. I bought a double stroller Tandum because I do not think my 2 year old son would sit back (in front of me) when he was pushed. However, walkers Tandum are very big and bulky.
If you and your husband / partner go almost everywhere together, then you can go with two different strollers, otherwise I would get a double.
