My daughter (now 6 months ) hates plain rice cereal. But if I add a bit of pear she will tolerate it. I was advised not to start on the six month food, till she had been on the four month food for a while, as even though she is six months, her body needs to learn to digest the food first, and the four month one is best for that. Anyway, try the pear or apple, and again give it a few days to check their is no reaction. Remember that everytime you introduce something new, it may take a few days for bubs to get used to it. While I'm here, does anyone know the best time to try custard? I can't remember when my first one started. Some brands have from 4 months, and others from 6.
