I know this has probably been asked a million times but I am wondering how one knows when to stop the DF? With DD1 I remember that she just stopped taking her first feed of the day all together. She was about 5.5months. DD2 is now 5.5months and I'm wondering how much longer I should continue the DF? She takes her feeds every 4 hours though out the day and has no NF for about 1.5months now. She takes purees once a day really well.
