My eldest mostly slept between feeds at that age. He'd be awake for an hour or so for feeding and changing and a bit longer once or twice a day. I am was a children's nurse and I put it down to that.
Then, 15 months later I had my second, she was awake most of the day right from the start. I was lucky if she had half an hour between feeds, maybe 45 minutes once a day. Longest sleep was from around 7pm until 10, then not more than an hour at a time overnight and didn't want to sleep even then. She didn't sleep a night through until she started walking. (And she could throw herself over the bars of her cot at months.
Every child is individual, they don't read the books, some will barely wake to feed, others (like my dear daughter) treat sleep like something to be avoided at all costs.
Routines help some, and it's definitely worth a go, others want to feed all day one day and really don't care another. Your baby is who he/she is, work with them and just try to relax.
Even my mum couldn't settle my daughter (much to her disgust) and I'm one of 7 so she had had plenty of practice, so don't think for one minute that inexperience necessarily makes a difference - although they do sense nervousness and that can unsettle them.
