i remember at 8 months old DDs sleep when crazy and it felt like it was worse than when she was a newborn. i think your doing the right thing and as much as it doesnt help in anyway, i think its pretty normal for some children to have a hard time sleeping through the night. DD used to be in her own room at 8 months but the sleep got SO bad that i ended up bringing her back into my room so i could get a bit of sleep and id bring her in with me on the first wake up, i got a bit more sleep and the wakeups thinned out a bit. hope it gets better for you soon.
