the.com/shallow end
Where confidence goes to float and toddlers pretend they can swim.
means The part of a pool (or a conversation, relationship, or life) that's safe, easy, and doesn't require much depth to survive.
from Literal in origin — pools have long been built with a 'shallow end' and 'deep end' to separate waders from swimmers. The figurative sense (someone being 'in the shallow end' intellectually, or a conversation staying in the shallow end) grew naturally from that physical contrast: depth as a stand-in for difficulty, seriousness, or risk, shallowness for ease and safety.
