One year!?!?!

Ok so my baby boy just hit his one year mark and I know its time to change somethings like formula to milk, no bottle, and no pacifiers and all regular foods well my baby is officially done with his pacifiers goin on two weeks but I'm having two issues one he is in this little thing where he doesn't wanna eat regular foods and only wants baby food the lil bits kind if he wants to eat which I don't know what to do I don't like it when he skips meals it makes me worry and also now the whole bottle and formula thing I'm not sure how to handle it so please any advice
