Should your baby sleep in your room? Room sharing not bed sharing. If yes, for how long? 6 months, one year, more?

My firstborn is already 4 years old but still co-sleeping with us together with my 10 months old baby. We love this arrangement; as sleeping is a "family" bonding time we do not have any problem with my kids not wanting to sleep at all during bed time where some of my friends (children sleep in their own room) encountered and spend hours to fight with the kids to get them sleep. There's no specific or a right timeline/guideline as to when the kids are "ready" to sleep in their own room as every kids are different. Trust your kids and your own Mommy's instinct instead of the calendar.
