we actually own 4 one for our holiday place, one at IL's one at my mums and one for travel...

anyway up till begining of nov jack slept in his at our holiday place no problem the one we have has a slight bit more padding than the other 3

he still sleeps in the ones at the grandparents houses no problem he is 26 1/2 mth old I would say we average 4-5 nights a month where he is in one
