Hi so sorry for late response.
I changed cereal and it is corn based, he loves it. No issues with discomfort. He is still napping 45 mins. Just the day before yesterday and today he napped for 1.5 hours it was a miracle. I am hoping that it becomes the norm.
He is almost 7 months, eating veggies, fruit, rice cereal, breastfeeding and taking about 8 oz a day of formula. He is a happy little man but the nightwakings are still exhausting and he has early wakings too. A typical day starts at 5:45 and ends at about 6:45pm with three 45 minute naps. I tried the DF but it didn't work. Any suggestions?
