Yes, you can try giving your 6-month-old baby Lax-A-Day for up to 10 days to see if it helps with their constipation. You should give them 6g of Lax-A-Day, which is slightly less than half of the 17g spoonful that comes with the product. It's also okay to mix Lax-A-Day in their milk. If your baby has a lactose intolerance, it's best to limit the amount of rice cereal and opt for oats and barley instead, while increasing their intake of vegetables.
