We just use half a scoop of powder with all Jennas clothes, and we do a double rinse. She's only ever had a skin rash once, and that was when we had used Omo front loader for a little while, so we are back to the cheaper stuff again!
That first load of baby clothes on the line nearly melts your heart - sooooo cute!!!
Word of warning - take any darks out and wash them seperately the first couple of times.

We are only just starting to put Jenna's stuff in wiht ours now.
