My twins just turned 4 months old . Most nights they sleep through the night. I read that at 4 months to start cereal in their bottles and it will also help them sleep better. A few days ago, I mixed 1/2 tsp in 6 oz of formula. That night they cried amd cried. I think their tummys were upset from the cereal.
They were born at 36 weeks. Also one baby is on Soy formula and the other is on Sensitive. Is there a certain type of cereal I should give them and how should I introduce it to them?
