Hello J. - There are chemical components in HUMAWORM For Adults that are fine for adults to take, but that are VERY harmful for babies. Here are the herbs in HUMAWORM that must be avoided during preganancy and while breastfeeding.
Wormwood can cause spontaneous abortion, Thyme is a uterine stimulant, Fennel increases estrogen in women, Cayenne can taint mother' milk to an undrinkable flavor. Also Burdock, Elecampane, Barberry, Cascara Sagrada, Senna, Sage, and Peppermint are not to be used.

When your child reaches 30 pounds and stops breastfeeding he/she may safely do a parasite cleanse. My suggestion is until then try to incorporate garlic into his food. Garlic on mashed potatoes, a little garlic on breadsticks, etc. You can do a parasite cleanse now, your wife and baby can eat more garlic and then do a cleanse later. I hope this helps!

Here is the info on garlic:
