Our 6.5 month old used to sleep well; put up/put down. She'd fall asleep on her own at around 8pm only to wake up once for feeding. She would then wake up around 5:30am to then be held to sleep till 7:00am (the last part I don't know why).
2 weeks ago, she started waking up every 40 minutes to 1 hour throughout the night. She would cry fairly hard as soon as she woke up and the cry would escalate very loudly if she was not tended to within 30 seconds. As soon as she's picked up, she falls right back to sleep and you have to hold for at least 3 to 5 minutes before putting her down. Even then, she would wake up again in 10 minutes.
As you can see, this makes sleep impossible for both working parents. We now have splitting headaches during the day and I'm afraid we will lose our minds soon.
My kid is very happy during the day and never cries during day time nap either. She only becomes difficult at night.
The thing is, we put her to bed at the same routine as before. She falls asleep on her own at 8pm every night.
What's wrong? Is there light at the end of tunnel? Please tell me this won't go on until she's 1 year old or even longer.
