Our six month old started solids a few weeks ago and we are already dealing with constipation issues.  Her stool is dry and hard.  She has breastmilk and oatmeal in the morning, formula during the day and breastmilk and veggie/fruit in the evening.  I am wondering if it is because the formula and oatmeal are iron fortified?  Or is her system just adjusting?  I know juice can help but I don't know if I am ready to give her a sweet drink this soon. Is anyone else experiencing this?  What is working for you?
