There are no strict rules about when you should stop co-sleeping with your baby or child - it all comes down to your family, your preferences, and your little one's wellbeing. You may want to stop and change to a different sleeping arrangement if you have other children and are short on space in the bedroom, or if you want to begin sleep training. However, you may find that changing the routine to having your baby or child sleep in their own room becomes trickier the older they are. For instance, a five-year-old who has slept in the family bed their whole life is more likely to show signs of separation anxiety or resistance than an 18 month old who has been following this routine for less time. If you have a child under 24 months who you are trying to transition into their own bed, you could try our Zen Sack, which is gently weighted to mimic your touch and help them self-soothe to sleep..
