PLEASE HELP!

Hi, so im new to this site but in my desperation my friend suggested i write on it to see if anyone can help...
My daughter turned 6 months on sunday just gone. She has always been a very good sleeper. Sleeping through the night from 3 months and we were extremely lucky to find a routine that worked with her quite early on; Bedtime being at 7 and waking up around 7.30am, with 3 regular naps in the day.

The last couple of weeks the routine has gone out of the window and bedtime was between 6 and 8, waking up regularly through the night and getting up no later than 6am.
I must add at this point Bella was very poorly and scarily admitted to hospital 6 weeks ago and has also moved to her own room but these factors didnt initially seem to effect her.
Now we are at a situation where the poor little lady cant settle. Her day naps are irregular and sometimes non existent but the most problematic thing is she wont sleep before 10pm, happy as larry but wide awake!
We've tried everything, and whilst part if me is putting it down to teething and other changes, and im not naive enough to think it was always going to be easy sleep wise, and thinks i should just go with her. I need to check if a) anyone else has experienced a sudden change in sleep patterns like this and b) any suggestions to help our Bella Boo?!

Thanks in advance xx

My first suspicion would be that she is overtired due to poor naps, hence being awake till 10pm (being overtired can make them completely wired and unable to settle).

I'd suggest trying to sort daytime naps out. She might be only needing two naps a day, so you could try for one in the morning (about 9 is a good time, but see what she does), then another after lunch. Try to make at least one of them over an hour.

If she self-settled before, it is quite common for them to need a bit more help getting to sleep. You might think she's not sleeping because she's not tired, but it's because she needs putting to sleep. So you could try the pram, car, rocking, feeding, anything that might put her to sleep. If she starts sleeping better in the daytime, you might find she starts sleeping better at night too.
