When do you think is a good age to start childcare? Would love to hear what age worked for you and why.

I believe emotional development comes from your kid's interaction with you, so he will be ahead emotionally if you wait till 4 years of age. But from my personal experience it all depends on your child. Some kids are very visibly shy and not willing to stay away from parents. My little one was very confidant and happy to meet others, so I chose 4 years. My advice, don't fall prey to social pressure or biased mindset of 'benefits of early adoption of childcare'. Find playgroups you can join with him and test, how does your child cope separation and do not follow the "sink or swim" approach.
