I am expecting our second DD in April and I am trying to figure out what to do about strollers.
DD1 will be turning 3 when DD2 is born. We currently have the Uppababy Vista, which could work with a rumble seat. The weight limit on the rumble seat is 35lbs and DD1 is 28lbs now. She is also in 97percentile for height, so she wouldn't have much space in there. Initially I thought this is no a good solution, but my husband brought up a point that DD1 may grow out of the stroller age very soon.
When did your children stop using the stroller?
One more consideration is that we do go on long walks regularly.
Re: At what age do kids stop using the stroller?
DS was 2.5 years when DD was born. He would still ride in a stroller but was also happy to walk along side us and was well behaved doing so. We chose to get a rumble seat for our UppaBaby and I think it was a good decision. We've only used it twice; once at the zoo and once at a large mall when we were there for a few hours. Other times he either walks or I would wear DD and he would go in the stroller.
My son was 3 when we had #2. We never got a double stroller. I kept the ergo in the basket of the stroller so the few times that he asked to go in the stroller because he was tired of walking, I then wore DS2 so dS1 could go in the stroller. We used a bumbleride flyer when he was a newborn and it has a full flat recline so we never used the car seat to make a travel system.
DS stopped using a stroller right before the twins were born He was just 2. The girls would prefer NOT to use a stroller... but they outnumber us, so I sort of force the issue.
DS at 2 would go on walks w/ FIL that would last close to 2 hours, and rarely would he need carried.
