Hi there, a few thoughts:
- the paci is a prop, if she can't replug and is looking for you to do it...have you thought about weaning?
- letting her sleep on you is also a bit of a prop, she's falling asleep after feeding? Ideally she should be going down into her crib awake at this point and getting to sleep on her own
- at around 9 - 10 mths they are typically having solids before milk, so I would also keep her feed times to meal times...with snacks in between.
- It's not that she's not tired, she's overtired. So she can't sleep restfully. Normally at this age they start to look to drop their day sleep needs, most do it before they are ready. What you need to decide is what works best for you and for her - long AM/short PM nap or short AM/long PM nap.
- any signs of teething or other discomfort? Perhaps some of the solids are disagreeing with her?
To be honest I think you need to get rid of the props and then work towards improving her naps. The nights should then get better by default.
