Is it a norm for a 8 month old baby to put toys into their mouth? I read that that is how baby senses n explore the things around them. Their mouth is like their senses . Is it true? Cos my baby will be gg to infant care this fri and I worry that by putting toys etc into his mouth , he will fall sick easily. How to prevent him from putting toys into his mouth ?

You're right, this is very normal and there is little we can do to prevent this. Their mouth contains the most number of sensory nerves and this is how they explore the world around them. And more so if they are going to infant care where the teachers will be watching over more kids. It's hard to avoid kids getting sick as sometimes parents bring their sick kids to school unknowingly that they are sick. Best you can do is teach your kids proper hand washing. Make it a habit. When they get home from school, wash their hands properly. Proper nutrition and outdoor play also boosts immunity. Hope this helps.
