We bought this in March of last year when our son was 5 months old and holding his head up without any problems. By far the best thing we could have bought for our travels. We do 6+ mile hikes almost every weekend. We've taken him to Hawaii, Peru, England, France, Italy, Switzerland and even just trips to the grocery store. This was so nice for museums like the Louvre where there are a lot of stairs. We just walked up them when other parents were looking for elevators with their strollers. We couldn't get into a couple of places in Europe because of the metal frame, even though we said it was aluminum, but overall most places just let us walk right through without much trouble. We used the rain cover when we were hiking through Cusco. We had a real torrent pour down on us and he was the only one who stayed dry. Also we had a large duffel bag already that this fit into when fully collapsed, but it flew inside that bag with no issues. Only real complaints I have are that my 3.0l Osprey hydration pack from my day pack barely fits into it. I can't fill it all the way up with water and even when I get it in, it often gets caught on the adjustable back part, so I have to reach in and hold that in place while I squeeze the hydration pack part in. Second is the sun cover can get caught on the screws while inside the frame. We tore a little bit of it when trying to pull it out. Also the sun cover goes into the bottom compartment section and is not separated from the compartment, so if you have diapers and such in there, they will eventually get in the way of the sun shade. They should add a separation of cloth so that it stays in its own section. My son is almost 2 now and quite tall for his age (37 inches) so we can barely buckle him in now because his torso is long. He only weighs 30 pounds so we're well under the 48 lbs limit but I feel we're reaching the end of it. Fortunately my 4 month old daughter is soon to be ready for it :).
