Please tell me about the 12-week growth spurt

[mpops]

So my DD started being able to tell day from night at around 4 weeks and since then, with some ups and downs, she would go to sleep between 8-9pm and wake up at around 3am and then at 8am. Not much daytime napping apart from in the sling/pushchair/on us. Then at 10 weeks she started sleeping through (almost). It was amazing!

And then the day she turned 12 weeks (4 days ago), everything was turned upside down. She is now waking up every two hours for a feed, her feeding is very erratic in the daytime, and she naps like a pro (three times a day for about an hour).

This all coincided with a lot of exciting new things happening to her, physically, mentally - she just seems a lot more rensponsive, excited, communicative, physically active. But also a lot more unpredictable.

Has anyone else been through this? It's driving me a bit crazy!

sadly you are likely to find that every time everything seems settled/routine goiing swimmingly that something turns it on its head, be it a growth spurt, teething, illness, excitment, visitors.... all sorts! there are loads of times where ours has slept through like an angel for a month or more and you think woohoo! cracked it! then something else comes up and for a week or so its all disrupted then it calms down again usually.... ours is 26months and slept through from 10wks to 10m then we had the teething horrors for about 4 months.... sigh :)

I know you're right. She just seems so unsettled again all of a sudden and I can't help wondering if I messed up somehow. Knowing that it might be a phase would be comforting and would help me just get on with it without worrying too much...
