L-Lysine - start with 5000mg a day for a few days, and you may want to take 500-1000mg regularly thereafter. Eat foods high in L-Lysine and lower in L-Arginine.
Melissa Essential Oil (true Lemon Balm) - mix about 20 drops with an ounce of carrier oil (fractionated coconut or sesame or emu...). Apply to sores a few times a day, NEVER redipping. Used neat (no dilution), it can be too strong.
Oregano Oil p73 - can make a dilution similar to the Melissa.
Both of those would sting badly if they get in your eyes so I would use the Melissa even more dilute (one drop per ounce of carrier), or not at all in that area.
I have only had them on my lips and cannot imagine the torment of more widespread sores. This regimen cut outbreaks down to 2-3 days instead of 7+ for me. Icing at the onset of sores can help too.
Wash your hands frequently and definitely before touching your child.
No kisses or face cuddles. As your baby gets a little older, his immune system will be better able to handle getting herpes which some kids will inevitably get from their parents.
Good luck. I hope you feel better soon.
