Baby rubs her eyes a lot

Kara
But she won't go to sleep!! I see her rubbing her eyes a lot. After waking up in the morning or a really long nap. So if she's still tired, why doesn't she just go to sleep? I want to tell her and understand 'if you're sleepy it's ok to fall asleep, I'll still be here and i'll even hold you while you sleep if you'd just go to sleep!!' She's 12 weeks and has gotten bad again about not wanting to be put down and won't stay asleep. We did well for several weeks and thought it was getting better like maybe she'll sleep thru the night now. Nope.
