When they sleep through the night and you think all is good, then they will decide they don't need two naps afterall.
Then they learn how to feed themselves and you think that is 20 minutes of freedom because you aren't holing a bottle or spoon feeding, then you have huge messes every meal and are on standby to fish the 30 cheerios they stuffed in their mouth .
Then they learn how to walk and you think your back will be saved from carrying them and then they learn to run and your legs hurt from chasing them.
Then they will learn how to talk and you will be so excited when they understand the meaning of certain words until that word they are saying is no and they say it while doing whatever they aren't suppose to be doing .
But one thing is true, you will love and cherish something about every stage. And always remember "this too shall pass".
