ELI5: Why do animals learn basic life skills (walking, eating real food, etc) really fast compared to humans?

For example, a dog can walk and eat real food by the age of at least 6-8 weeks. A human can take up to a year or longer for those same skills. I'm sure this is the same in other animals. Why is this when humans are vastly superior to animals in capabilities.

It was an evolutionary trade-off. Our large brains helped us survive, but they made child birth difficult. As skull sized increased, either babies had to be born earlier with fewer initial abilities or the mothers had to have larger hips. The larger hips made it more difficult to run upright and thus survive, so over time, children were born earlier.
