My bump always seemed to know when to expect meals too! Like yours the afternoons were the quietest, but the evenings were definately riot time.
Even after "duracell bunny" DS was born the same sort of pattern applied and he's never conformed to the amount of sleep that babies are expected to need at any particular age. In particular the "in bed at 7 and sleep for 12 hours, with a couple of long naps in the day" pattern has been a total non starter for us - he simply has too much energy/stamina, and you can't make them sleep if they're not actually tired. It's taken us 14 months to get nighttime sleeps down to 8.15 in bed/6.30 up - it used to be nearer 10pm/7am.
Yes he's ultra active - he's always the one with loads of energy left when I pick him up him up for nursery, so he's running around when the others are having songs, or books read to them by that time of the day. The upside of all that activity is that he did hit all the physical developmental milestones really early (rolling at 8 weeks, sitting up by 5 months, crawling before 7, walking with a pushalong or hands/held at 8 and independently at 10, running at 12, etc).
One thing you might find if bump does turn out to be a very active baby is that he/she like to lie on the floor to wriggle about more than you'd expect even when he/she is tiny. My DS, from a couple of weeks old, was always much happier if we were out if I took along a small play mat and a toy so he could play, rather than be held or sat in his car seat. He loved - and still takes to bed now - a snake which would lie on top of him and appear to move when he kicked his legs. The activity arch was a big hit from very early days too.
