We used it for 6 weeks only, but our boy was (and still is) massively tall and broad (15kgs at 14 months)! He outgrew his capsule at 2 months too, so I don't think our situation is anything to go by! Some friends used it for their 6 month old babies for day naps when they came to visit, if that helps? With the benefit of hindsight, had I known we would be having a giant child, I may have just popped him in the cot right away and forgotten about the bassinet altogether. Perhaps if our next bub is a girl she will get some more use out of it! Just great quality and very sturdy - so I don't regret the purchase
