Car seat cover

I love this car cover from Brica. It fits almost any car seat. I have used it with a Peg Perego and also this Britax car seat. It does a great job shielding from the sun (on the top), protecting from rain, and also keeping bugs away from baby. Even indoors, it gives baby a more secluded feeling which makes it easier for him to sleep. I'm happy with the quality - it has lasted almost two years so far with two babies.

Currently $25 at Amazon.

No Sleepovers?

I share all of the concerns mentioned in this post. I'm glad I wasn't assaulted or anything, but I got in plenty of trouble because of a lack of supervision. Sleepovers were a net negative in my childhood. And I'm still dealing with the fallout.
