You have been a little spoilt, TBH. But then I'm lucky as I'm very spoilt, as my DSs have usually woken up naturally around 7.00 am. Sometimes my DS2 will wake up around half an hour earlier, and I have to get up with him.
However, if you want to get a little bit of extra time, there are a few things you could try.
Firstly, you have to make sure her room is DARK. If she wakes up and the sun is up, no way is she going back to sleep. TBH, it really needs to be too dark for her to see her toys, so apart from a cuddly toy, no point in giving other toys in there. Buy some blockout lining if you need and attach it to the back of the curtains, or temporarily drape a blanket over the windows.
Secondly, you could get one of those timed clocks (sleeping bunny, etc) and set it for 10 minutes later than she is waking up. If she knows that you're going to come in when the clock lights up/changes picture etc, then she might settle down for those 10 minutes. You could then VERY GRADUALLY stretch that out to 15 minutes, and so on. But this may not work!!!
Also, you've taken away her comforter, her dummy. Could it be replaced with something? DS2 replaced his dummy on his own with muslin cloths. Sucks on them like mad!!! Not ideal, but for me better than a dummy (and replaceable if lost unlike other types of comforters!!!)
But if this doesn't work, then you will just have to get up. At least until she's old enough to get up on her own and amuse herself safely, which won't be for quite awhile yet.
