Ive heard about just piercing the teat hole so it opens up a bit but its not as fast as next level teats that could do the job!
I got mam ones because he likes them dummies and no other ones like tommee tippee. I just have normal ones they are absolute shit espesh because I catch him creating bubbles in the bottle. He'll be that kid who no matter what will blow air bubbles in his fizzy drink with a straw hahaha he did however nail his bottles. 5 oz last night well more on his night feeds and a good 6 oz this morning nailed it. The avent ones do the job with te bubbles but he fusses too much on the teat.. It's such a ballache! Got a teether from mam on offer in Asda yesterday too I see his little teeth coming soon ! If you get like a microwave boxy thing fill it with cold water not completely full bang your bottles in their take all the parts apart shove it in for 3-5 mins will do the job too. We refuse to use the sterilising tabs because of the warnings on the side my OH got a shit fit reading it and said boiling water will be just fine! And if you sterilize em before you go out and seal em tight there would be no need to sterilize them again with an on the go sterilizer as you probably can not rinse it off.
Oh and Dani does your avatar not look dayum cute! He's grown loads! x
