Some more useful baby ideas

I was thinking over the weekend that the following items would be useful for the new baby:

• Diapers that turn blue on the outside when they are wet on the inside.  This isn’t so much for the number 2s as it is for the number 1s; all the fathers out there know what I mean.
• A clip-in system for the Baby Bjorn (or other “tactical baby retention system,” as I like to call it).  You will wake up your baby every time you have to move her from the car seat to the Baby Bjorn, so why not just have a way that the Bjorn can unclip from the chest harness and clip right into the car seat.
• Self-applying diaper rash cream.  Seems like if they can figure out how to get Neosporin pre-applied to a Band-Aid and anti-microbial protection built into a sock, that companies should certainly be able to build rash protection cream directly into a diaper.
