Vicky maybe start with pears? with no rice cereal or anything just to help his body adjust to solids and pooing. I know that pears are easy to digest and they help fight constipation so maybe they are a good first food I know thats exactly why I started Jovie with them, pumpkin made her tummy ache & constipated her so I waited 5 days and then started with pears & she's been good ever since, even having pumpkin.
