my bb (13 months) used to sleep at around 8:30 p.m. every night till next morning around 6:15 a.m. (wakes up once or twice in midnight and can sleep again after we pat her).
suddenly, yesterday night, after we take her inside her room, she starts to cry and wants to go out, after she goest out, she stops crying and is very active, we try to take her again to her room after she calms down, yet, she cries again. This repeats a few times till 11 p.m. , she finally sleeps.
tonight, she still cries when we take her inside her room, then, we come out, luckily, at around 9:15 p.m., she finally sleeps.
just wonder why she does not want to sleep suddenly?
