My dd is seven months now, and it's only now that my breasts have stopped exploding every five seconds!
I have tried the following:
Lilypadz - cant see them under the tops, expensive but reusable but I found that if I leant againt my side, the suction would break and any milk already collected would gush down my top. Probably a good thing to use once flow settled down.
Avent reusables - I brought a pack of six and had soaked through all six within a day. Hate them. Highly pattered as well and visible through my top, worst buy I made!
Avent disposables - highly absorbant, no sound effect, hardly visible under the tops. Got the sticky pad thing as well.
Tommee Tipee disposables - sound effects galore but v large so not too visible. Very good absorbancy as well.
Tesco disposables - fairly absorbant but very visible unfortunately.
Morrinson disposables - not very absorbant
Boots reusables - the best reusables I have tried. They wash well, you cant see them under clothes and no sound effects.
HTH!
