It's so hard as mums to know what is the right thing to do. I personally overloaded myself with research and still found it hard to decide so just went with the WHO and ABA recommendations.

Manta, I had thought that you should delay the introduction of nut based foods till after 12 months. By the sounds of things I must be on the wrong track (probably all that research I did months ago has left me confused). DH has been dying to give DS some peanut butter, I guess I should let him....

Lady Noor I tend to agree with what the other posters have said about introducing solids at 4.5 months, I definately didn't see any improvement in DS's sleep when I introduced them at 6 months, if anything his sleep actually deteriorated. Like your LO my DS was a fabulous sleeper until he reached the 4 month mark. Before that he would sleep through pretty much every night. I tend to think that at around 4 months they develop a much greater sense of awareness and the sleep issues are related to that. Are his weight gains good and is he having plenty of wet nappies? If he is I would take that to be a very good indication that he is getting enough iykwim?
