Pinoy moms and dads, until when (what age of child) do you plan to co-sleep with your baby/toddler/kid?

We have been co-sleeping since the day they were born. My eldest is 3.5 years old and he still sleeps while breastfeeding. I know that this co-sleeping will last longer than what I thought. And I'm loving it! I can't even sleep a night without my babies beside me.
