I have two boys 4 years apart. Youngest is 1.5 and adores his big brother. Older brother really wants nothing to do with the toddler. To be fair the toddler attempts to destroy a lot of things he makes so I understand it. And the age gap is a bit much at the moment. However I want them to at least kind of get along when they are older kids/adults and unsure how to start encouraging it. Those who kids get along do you think it’s just luck or something you did to help?
