OP here, getting desperate
Baby was having a breakfast of 1/2 piece of dry toast, a little cup of plain Greek yogurt (4oz) sweetened with fresh pineapple pieces. Mom told me to take away his breakfast after he only ate half a yogurt and one bite of toast!!!
I adore this family, they are really great- until it comes to this issue!
Thankfully I am taking him to his pediatrician today to discuss; instead of having a lovely day visiting the art museum and playing in the park!
