How much sleep is your baby actually getting?

Hi Mums! 

Just wondering how much sleep your baby is actually getting in a 24 hour period? 

My 8.5 month old will only sleep 10 hours overnight (she sleeps through with no feeds) and 2/3 hours during the day. 

So much information on the Internet is suggesting she should be sleeping 12 hours over night and nap for 2/3 hours during the day but I'm wondering how realistic this actually is. 

I would be interested to see how other babies are sleeping. 

Thanks xo
