DS scared of high chair tray

Every time i go to put the high chair tray on he freaks and acts scared and spesh when taking it away, just when he's used to the tray being there I take it away and he jumps out of his skin and clings on tight to the tray, occasionally he has been so scared he has cried ...
I feel so sorry for him, he normally isnt scared of any thing , so being scared of a beige high chair tray concerns me..

The tray is loud when it clicks in or out and i always warn him and sow him what im about to do....

he just sits and whinges every time he in it ...
He about 6 1/2 months old and i have no clue what i sohold be doing or why hes like that .... :(

Nina absolutely hated her highchair for about 2 months. I used to have to feed her either in the bouncer, on my lap or on the floor. Hopefully it's just a phase he's going through.
I'd suggest keep trying it, but not at every sitting, maybe every couple of sittings give it a go.
