Tips on getting baby to latch?

R
Any tips on getting baby to latch? He will sometimes, but gets so frustrated and rips off. I'm not sure why I keep trying and if I just cannot get him to latch after about 15 mins I give him a bottle.  I've been pumping to keep my milk coming and I've had to bottle feed him quite a few times just because I feel like I'm starving him! I know it's just tough but any tips would be greatly appreciated. I refuse to give up.
