For the First Curse, Regina wanted to bring the people she wanted and since she met Victor/Dr. Whale, who pretended to try to bring Daniel back, she got him.

For the Second Curse, since Snow met him in Storybrooke and since was well on her way in pregnancy, he would be pretty handy to have around.
