My little Ace still sleeps next to me even though he is 16 months now. Even if we go home to Naga.
The cots and his expensive mattress (99 pounds) hasn't been used though it was his grandad who bought.
I love it and enjoying it.
I believe that they will grow out of it. Like my 14 year old son, he just wants to do what he needs with school and that. So its better to make the most of it while they are still young, when they grow up.. that's it.
Well, that's the culture talking.
Though I must admit that I admire the western culture as well for teaching self reliance at very young age.
