My baby is 11 months old and started sleeping through the night quite early. However recently he would cry for no reason in the middle of the night randomly (though it happens most often from 4am) and at times he would sit up to cry. It would take me a while to put him to bed and calm him down..... Any advice on what is happening and how to solve it? I tried CIO one night and I really feel it is not for me nor him - so any advice other than CIO is much appreciated. We are very tired and want our sleep back. Thank you.....
