i would absolutely encourage you NOT to continue letting lo cio!! you are only making matters worse by breaking the trust that you have established with your lo over the past 8 months!...and in the end it will take much longer for you to build that trust up again than to just deal with the sleep issue on its own.
with that said, from what you said i doubt it is a hunger issue. if you do not feed your lo when she wakes what does she do? have you tried shhing in the crib and not taking her out? pu/pd? how long before your lo falls back to sleep??
i may try extending the morning A time a little bit longer, although it is supposed to be the shortest A time of the day, it does seem a little short for a lo that age. it does seem that your lo is getting quite a bit of daytime sleep also - which is why i asked the questions earlier ..about what your lo does if you try and settle in the crib etc...my lo started waking and wanting to play - not by herself (would have been wonderful if it were that easy
) but of course with mommy! i had to tweak her routine and not 'stick to a schedule'. when i went by what my lo needed and not by what 'time' it was she started sleeping better. all lo's are different and it may not be daytime sleep related, but it seems that may be the issue here. sometimes my lo will go 3 1/2 hrs between feeds, sometimes up to 5 1/2 hrs!! and still not wake for a feeding at night. she is now down to 1hr naps/2 x /day...wish they were a bit longer still - but she doesn't need it.
