Ever since last night my baby won't eat very good, or even at all. She is 4 months old, and she cries like she is hungry but then when I go to feed her she won't take it. This morning I feed her but she only took one side and she usually takes both sides. And she hasn't eaten in 4 HOURS and she won't take either side. She usually eats every 2 to 3 hours. What do I do? Is it something I am eating? Is something wrong?
