My dd is almost 15 weeks and is ff. We use Avent bottles with size 2 teats at the moment. In the past week or so, she's started sucking the life out of the teats as if he milk isn't flowing out fast enough. It's causing the teat to collapse which makes it harder for her to feed. I'm assuming this means we should go up to size 3.
I have about 8 bottles so buying 8 new teats will cost a small fortune! Is it possible to just poke an extra hole in the size 2 teats with a sterilised pin, or should I just suck it up and buy new ones? If so, what's the best way to do it? I don't want to ruin the ones we already have!
