7 Month Old Can't Sleep Well

I agree taking him to a doctor, but I would try putting some nice quiet, soothing music in his room to play all night............maybe on a radio station. This worked for me.........
Also, is he getting enough food before he goes to bed? You might add a little more food to his last meal or snack..........my son ate way more at that age than most, but he was a big boy! So I added cereal to his bottle.......they make bottles for that.....at least they did.....

Good Luck and take care.

Oh boy!! We had one of these babies too and I was a walking Zombie until I did something about it. Rule out medical reasons such as reflux oe anything else and if your son gets a clean bill of health then it's time for tough love....SLEEP TRAINING. It is a giant misnomer that babies know "how" to sleep. No, they don't. We have to teach them. If left to our own vices, even as adults, all humans will sleep on what's called a Circadian Rhythm. The reason why we don't is because society tells us and shapes us into sleeping the hours and times that we do. There is a wonderful and Godsend of a book called Healthy Sleep Habits, Happy Child written by Dr, Marc Weissbluth. Get this book!!! This was my bible and it turned my up-every-hour-on-the-hour youngest child into a peaceful and predictable sleeper. Down by eight, up by seven and two naps religiously...9-11 and 2-4....every day, rain or shine. I am NOT joking. I sleep trained her with this method from the book. Took a total of one week to get it all down but once it was down, it stuck for life. Be prepared for one hell of a week or two though. Sleep training is not for the weak at heart or those who cannot commit and finish the plan. You will endure your son crying a lot and without you to comfort him. He has to do this or you will soon have a toddler sleeping in your bed and never having a sense of peaceful and restful sleep.....in his own bed! This happens when parents don't realize that falling to sleep and staying asleep is something that we, as parents, must teach our children to do as babies and enforce the plan consistently as they grow up. I am happy to report that I now have two incredible teen daughters who are fanatical about their rest and what good sleep means to them and their bodies. No problems here. I also just helped my brother and sister-in-law sleep train their first baby and it was the same great success story. She began sleeping through the night at 8 weeks and we trained the little tater tot to take two scheduled naps of 1 1/2 hours long at designated times during the day. It's like pure clockwork for them now and my neice is a happy and thriving six month old! Find that book, grab some time to read it, gather yourself and your husband for the job that lies ahead and dig deep. Be strong. Put it into action. It will be the best worst two weeks you have ever had AND,,,,if you have another child, you will already know the secret to sleep training the right way. Good Luck and start sleeping!

My suggestion is to make an appointment with your pediatrician in case it is due to a medical issue. Once that is ruled out you can focus on ways to help him sooth himself back to sleep.

Is he hungry? He could be going through a growth spurt and need some extra food. What about teething? Getting new teeth can be very painful. But like other posters have said I would get a check-up from the doctor to rule out any medical problems.
