It's amazing how children grow and change. Until you are around them on a regular basis you never remark on what things must be taught, but also what they pick up. I've heard children compared to sponges, always observing and mimicking the behavior they are surrounded by.
Recently I've been working on manners with the girls. Please, thank you, your welcome and best of all chewing with our mouths closed. Mirna was so proud of herself for being able to eat politely like a big girl.
