Leaking Avent Bottles
I have a 7-month-old son and we use the Avent bottles for pumped breast milk. We have used them without instance since he was about 6 weeks old but lately they have started leaking. This has never been a problem before. Has this happened to anyone else and does anyone know if there is a fix for this? I have checked AGAIN and AGAIN to be sure they are together properly and they are.
