12 week growth spurt

My dd is 11 weeks, but was just wondering when / if you started noticing changes indicating this next growth spurt?

I started noticing he wanted to sleep a ton during week 13, and then this past week he's been eating like a fiend.  I guess we hit ours a little late.

She had a few bad nights of sleeping in her 12th week waking up every 2 to 3 hours, which is not like her. Then she started reaching for toys and bringing them to her mouth, and she started sleeping for 6 to 7 hr stretches at night. It's as if she needed a few extra meals at night to help her get stronger!
