Brief Answer:
Environmental factors play major role

Detailed Answer:
Hello and welcome to Ask A Doctor service.

I have reviewed your query and here is my advice.

In psoriasis, environmental factors are said to play major role. Genes play minor role. So if the environment remains the same then there is probablity that baby may also develop some symptoms. Since he also carries mother's genes, so probability of having symptoms will be much less. Environmental factors include skin injury, stress, cold weather, alcohol, some medicines and unclean food or water. So watch out for these in your child's case.

There have been limited studies on effect of fathers methotrexate on baby. Research shows that your baby will be free of any side effects of methotrexate.

Hope this helps. Let me know if I can assist you further.
