You started eating baby food in June (when you were 4 months old).  You started eating rice cereal when you were 3 months old.  The doctor told us to put you on rice cereal because you were not sleeping through the night (she felt the milk was not enough).  Also you had acid reflux.  You would throw up so we had to put you on a special formula.  Eventually feeding you before you went to bed and cluster feeding you during the day helped you not wake up every 2 to 3 hours.  You started only waking up 1 to 2 times at night.  Then you would wake up only once.  You started sleeping through the night when you were about 1 1/2.
