How did you successfully get your little one to love his/her lovey?

I recently bought Will an A&A lovey, in an effort to help him have something to calm down with to nap (working on naptime over here!) I have a Jellycat (rhino) too that we've had since birth, which I thought would be his lovey but I'm wondering if the blanket will work better.

I've heard the following works, but I'd love additional insights:
1. hold the lovey during feedings
2. offer every nap
3. offer when crying/upset
