The potty.

Thomas is almost potty trained.  He's so close.  I'd say that 85% of the time, he makes it to a toilet.  I never expected this process to take so long.  There are so many pinterest pins that explain how to make potty training happen in a day, a week, etc.  Nobody ever says it can take months to perfect. 

I suppose that it must be done, but I'm pretty sure changing diapers was much simpler.  Why is everybody in such a hurry to potty train their children?  I know that it's probably the cost of diapers, but after cleaning poo out of multiple pairs of underwear, I'd say the money is well worth it.
