My daughter is of 1yr 9 months .... she doesn't sleep at night constantly. She sleep disturbed and always wakes up midnight.. I am very much tensed... Why this is happening????

Hi, Please do not worry as it is normal in babies this age. They are growing up so fast physically and mentally that this causes changes in their sleep patterns. They Ard learning and picking up so many things at this time that it affects their sleep. It is just a phase and it will pass and she will have consistent sleep schedule. It happens with all babies. Also you may also address colic too. This too may be one of the reasons.
