9mo dropping feeds

Lately my DS has really started to drop BFs and I'm not entirely sure if it's normal or not.

At about 8 months we moved his midmorning bottle of EBM back to midday as he wasn't showing interest in it anymore so his routine went as follows:

4am - breastfeed and back to bed
6.30 - sometimes a small top up BF
7.00 - breakfast
9/10 - snack and nap
11.30 - lunch
12.30 - bottle of EBM
1.30 - nap
3.00 - BF and snack
5.30 - dinner
6.30 - bath, small BF, story, brush teeth
7.00 - bed

NOW, it's like he wants nothing to do with boobs or bottles. We think his top teeth are working on coming through so it could be a nursing strike but I'm not sure. Here's his routine now:

2am - BF
6.30 - small BF
7.00 - breakfast
9/10 - snack and nap
11.30 - lunch
(not interested in bottle or boob feed)
1.30 - nap
3.30 - small BF
5.30 - dinner
6.30 - bath, story, brush teeth (NOT interested in bottle or boob feed)
7.00 - bed

So, basically he's feeding in the wee hours and then is not really that interested in have anymore milk until around 3/4 in the afternoon and then that's it until his breastfeed in the middle of the night. It just seems wrong - Any ideas???
