Will my divorce have any emotional effects on the health of my two year old son?

It honestly depends on the relationship that you and your ex-spouse have in the future. If both of you are constantly bad-mouthing about the other to your child, your child will grow up confused and angry. I grew up in such family where my mum talks bad about my dad, and my dad talks bad about my mum. Needless to say, I grew up quite rebelliously (so did my younger sister). Now that they're older and mellow down, I find myself closer to them than before.
