Your almost right, but in english DO NOOOOT call a person or baby as "It" because " it" is only for things or objects and sometimes animals. You have to use pronoun She or he when referring to a person or baby. If are talking to somebody about their baby you should say " Awww, he/she is so cute!" Or " Aww, he/she is so adorable" or "Aw! How cute of a baby she/he is!!
