My 1.5-year-old daughter had good constant sleep and eating patterns, until she became ill. During the illness, her sleep and eating patterns changed a lot (and this is normal).
But after recovering, she is still in the same sleep and eating patterns as during the illness. She wakes many times at night, refuses to eat, wants to be held all the time, etc. Just like she turned into 3-month-old infant.
Should I go through the whole cycle again (train her as if she is younger), or there is some 'magic' switch to return to her normal state?
