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????

this is not a health issue, but more of a growth spurt thing and a passing phase. take care of a few things - 1.make sure she eats a filling meal before bedtime. 2.take her to the toilet in the middle of her sleep as sometimes kids wake up when they feel the urge to urinate 3.check that she does not feel too warm or cold during sleep 4. gently talk to her and pat her back to sleep
