When you say you have submitted to directories - which directories? Try to stay away from "general" web directories as much as possible - there are a few of these worth listing on but they are generally paid directories and they will only increase your site's "visibility" to the search engines and not directly drive traffic to your website...
Niche directories on the other hand help to increase your site's relevence in your niche and may also drive a few visitors to your website... Try searching for directories for catering equipment, mums and babies etc (the stuff you listed above) and then link (if the directory allows it) to the relevent page on your site.

General forum posting won't really help too much - it may drive a few visitors out of curiosity and there is a small chance that a big / long running thread maybe indexed and ranked well for certain keywords / phrases but generally forum post's on busy forums just drop off the radar... Finding niche forums though is an almost sure fire hit - get yourself registered on forums that target your audience, add a signature link and then participate in the discussions - this is the important part, if people see you as a "good guy" then you will be accepted into the forum community, otherwise you will be seen as a "nasty spammer"...
