Natty was having 2 or 3. TBH, I found her day sleeping did not make any difference to her night sleeping. (I kept a journal for a couple of months noting all sleeps and feeds because I was desperate. She too was waking 1-2 hourly overnight at that age.) But I know loads of others will testify otherwise, and of course it's always worth trying something different to see if it works!
Natty would have 45min-1.5hours in the morning, then the same in the early afternoon, then a later afternoon nap of 45min-1hour.
