This is my first post so please be gentle with me! I'm currently desperately trying to get my breastfed 16 week old to switch to formula but he refuses to take a bottle. I must've have spent nearly £100 on different bottles/teats and only once has he taken 2oz. Am I making it worse by changing? Do I make a decision and stick with one type of bottle or continue to try others? Any other tips greatly appreciated..
