I am on xanax (alprazolam) i have tried weining my six week old to formula however it just causes her constipation pain! breastmilk is the only thing that gives he?

Talk w/pediatrician: Please discuss this with your pediatrician. Your baby may not be ready to wean yet -- 6 weeks is very young. Or, she may be intolerant of some of the ingredients in the formula. There are many to choose from. Incidence of adverse events in infants exposed to benzodiazepines (like xanax) in breast milk, is low -- not zero, but low. Your bonding together is also very important.
