I wanted to wait a couple of weeks before I jinxed anything, but we have finally had success.
Noah is now 5 1/2 months old and on his 5 month birthday, we moved him up to his own crib and also started to feed him cereal 3 times a day with breastmilk. The first night wasn't that bad, as he only woke up 3 times. The second night was awful! The third night through the present was great!
He goes to sleep around 6:30 each night and only wakes up once between 2:30 and 3:30 a.m. to nurse. Then he'll lay back down until about 6:30 or so! It's been great...FINALLY.
Even last night, he was out by 6:00 p.m. and then slept until 4:30 a.m. He nursed and then went to sleep until around 7:30 a.m.! PRAISE THE LORD!
Mom and Dad are loving this sleep!
