My 9 week old son has just started sleeping through the night. He normally sleeps from 8/9pm to 6am. The first few nights he did this i woke him up about 4am to feed him as i was worried about him going too long without food. However, the last couple of nights i have let him sleep through to see how he is. He is formula fed. He has a good feed before he goes to sleep and a good feed when he wakes up. He actually seems more settled during the day as previously he struggled with trapped wind. My instinct is telling me its ok, as he seems happier. I just wondered what opinions you may have on this?
