Hugs honey, it's a rough ride with viruses and teething at this age.
I have to say, that seems like a fabulous amount of sleep for a 13 month old. Has he always been high sleep needs as far as you are aware?
I'm sorry I have a few more questions for you. Do you have to replug his dummy at night? When you're up with him every hour, do you feed him every time? Before all this started was he an independent sleeper?
I'm sure we can help you get things sorted, I'm sorry for all the questions. Xx
