I have a 12 week old baby boy and I'm breastfeeding on demand. Only he doesn't demand very much!
This morning I fed him at 6.30am, 8am and then nothing until 3pm. So that's 7 hours without a feed 
I offer more often, but he refuses to latch on and gets upset 
He goes to bed at 7 and wakes up once in the night to be fed, around 2 or 3am, so it's not like he's feeding all night either.
I guess he's getting 5 or 6 feeds a day.
He's only been like this recently, for about 2 weeks. Before this he fed more often, around every 3 hours in the day.
He hasn't been weighed for about a month, but I would guess he's around 15lb and he looks chubby, so I'm not concerned about his weight.
My DD was the complete opposite and fed all the time, around every 2 hours thoughout the day and cluster fed in the evening. This is my only other experience of breastfeeding, and as DS is so different I'm wondering if it's normal or if there's something wrong?
