Sisko loves babies, in any shape or form

he really does and it’s one of the most endearing things about him

(early on in DS9 I really didn’t like Sisko because I felt he lacked personality and warmth; later on I’ve come to see this as early Sisko having his personality very muted by the depression he got stuck in following Jennifer’s death, and the emergence of a more charismatic and exuberant personality is not just character development by the writers and Avery Brooks but Benjamin getting his real personality back - but I always enjoyed how affectionate he was with Jake)
