Can My Baby Sleep with a Lovey?

Q&A on sleep risks

What is the risk of introducing a small lovey during the night in the crib at 9 months old? My formerly good, independent sleeper seems to be going through a phase of separation anxiety and wakes up screaming for us and just wants to be held. I gave her a lovey, and she slept through the night again, holding it all night. I know the official guidance says to have nothing in the crib before 12 months, but I’m wondering about the true risks.

—Tired Mom

Public health advice is often overly conservative. There is sometimes an attempt to (using a phrase from Talmudic studies) “build a fence around the law.” Having a lot of soft items in a crib with a newborn can be dangerous and increase the risk of suffocation. In attempting to avoid that, we get public health advice that goes much further — nothing at all in a crib up to a year — in the hopes that even if people bend this a little, they will not bend it so far as to be close to the dangerous outcome.

This is also why, I think, the CDC says you should cook your burger until it is well-done.

The problem, of course, is that this can make it hard to figure out what rules are really important. It also means there is a big range of things that are actually quite safe to do that are ruled out.

This is a long-winded way of saying that it is totally, completely fine to give your 9-month-old a lovey. The risk of SIDS goes down dramatically after the first few months of life. Risk of suffocation is far, far lower with a child who can move their head around, roll over, etc. Also, a lovey is typically very light and thin and extremely unlikely to be a suffocation risk.

My only advice: get multiple versions of the same lovey. Otherwise, it will never get washed.
