Dear Ghazal
Best bet is to take your twins in for a full in person casetaking done with a trained Classical-homeopath.Guess work will not help your babies.............A proper visit with a practicioner will.
www.homeopathic.org
has a directory of homeopaths for each state.
Can you answer One question from me;
Were these twins vaccinated?
If yes.......When?......with what vaccine?
Zantac,and Prilosec have severe side effects on grown adults,To prescribe these to a 3 month old is not wise.Dont know if these drugs are even allowed to be prescribed to a Baby!(danger to the liver)
Google; Prilosec adverse reactions and see what comes up-do the same with the Zantac.
One should ALWAYS research drugs prior to taking-
