You may have been married for 2 years and 10 months but you have a child of six years of age which tends to suggest that your relationship is longer than simply the length of the marriage and it will be treated as longer.
In general assets acquired before the marriage - whether pensions or capital - and NOT mixed in any way with the matrimonial assets will be non-matrimonial. But, and this is a very big but, if fairness requires it non-matrimonial assets will also be divided. That is because 'needs' trump just about everything else. Non matrimonial assets will only be ring fenced if needs can be met without recourse to those assets. And needs are generously interpreted. It does not mean that simply being able to subsist adequately addresses need.
Capital and pensions are of course different classes of asset. Needs may, for instance, require recourse to non-matrimonial capital but not to non-matrimonial pension assets.
