refusing feeds

[mrs h]

Hi for the past 3 days now Judah has been refusing feeds from the bottle and screaming and crying and not taking any feed.I have bottle fed and breastfed ever since he was born so its not like ive just introduced bottles.
He is 14 weeks old now and he has had formula as well as me breastfeeding.
My problem is now he seems to be fussy but i havent the milk for him to have breastmilk all the time as i am at work and i can only express small amounts and the problem seems he wants to now breastfeed rather than have anything from the bottle.
Is this signs he is being fussy or he wants weaning because hes not satisified with milk on its own as he can be fussy on the breast as well.
does anyone have any ideas why he is doing this.
I should add he isnt ill or i havent changed formula feed.

Charlie did the same thing at 16 weeks, i was advised by my hv that losing interest in his bottles is a sign he wants solids so at 17 weeks we started weaning. Charlie is a big baby, at 17 weeks was 16lb 8oz so think he definately needed it.
