Hi--
I totally understand--both my boys are terrible sleepers unless they know Mommy is nearby. I agree with the person below--The Baby Whisperer and Dr. Sear's offer good solutions. A word to the wise--there is a lot of evidence that the CIO method creates a distrust between parent and child that later develops into emotional problems as the child grows. A baby doesn't understand why the person who is his safety suddenly disappears and gets very distraught. This causes the adrenal glands to release adrenaline, making it harder for the child to sleep. Because the brain is being "wired" until about age 4, this trains the child's brain to become more anxious. Eventually a baby will go to sleep not because they have learned to self-soothe (which is a higher brain process that takes logic) but because they become conditioned to knowing that their needs will not be answered. Not exactly a way to create a child who trusts his environment. (Can you tell my degree is in developmental psychology). So the other methods that do not involve CIO are much kinder and will keep that all important trust between you and your child.
Also, my children did not sleep well because they both had various digestive problems that caused discomfort. They say that a Mommy holding her baby is as effective a pain-medicine as giving the child two aspirin. That is why my children wanted me close. They both have food allergies. Allergies for sure cause sleep disturbance not just because of pain, but because the histamine and cortisol released during an allergic reaction is incompatible with sleep. Signs to watch for are constipation (defined as not going at least once a day), dark or puffy circles under the eyes, rashes of any kind, tantrums, clingyness, a need to suck all the time, being over-weight (because of that need to suck all the time), wheezing, coughing, post-nasal drip, frequent ear infections, and swollen tonsils without a clear sickness. If your child has any of these symptoms I can for sure help you in deciding the next steps to help, so please don't hesitate to ask.
Good luck!
J.
