For the past 3 nights, my 14 week old has been so hard to put to bed. I have been doing the usual bedtime routine. She usually wakes up around 7:30/7:45 am and takes 4 naps before I try to put her down around 8 to 9 pm. However she is going to sleep close to 10 pm now after waking 3 to 4 times from the time I try putting her to bed, waking up within 10 mins of her being out down asleep everytime. She hasn't done this before, maybe waking up once but not multiple times. Advice?
