I tried the whole feeding on demand, but that only drove me crazy because I could not figure out why he was crying, especially after just feeding him. Then a wonderful friend introduced me to the book My First 300 Babies. This saved my live:) I put Little Guy on a schedule and we were all happier with the outcome.
In this book it says to start potty training when your child turns one. This is not what everyone says to do it now, but this is a very old book:) I started today putting him on the potty and he did very good:) here is a picture of Little Guy trying out his new potty chair:) He really liked it:)
