Pregpan, Lindsay had a heap of hair too and it made it really hard to get to the cradle cap. Perseverance is the key to beating it. I used either baby oil or olive oil on him (whichever I had handy at the time) and would put in on his scalp about 1hr before his bath, then just before his bath, gently comb it off with a fine tooth comb. You can use sorbolene, bepanthen cream, or Tracey has suggested a paste made of bicarb soda and water, but I found that using sorbolene on Lindsay wasn't as effective as it just matted his hair and didn't quite get to the cradle cap properly.
