We have carried out lunar occultation observations at λ = 2.2μm at the WHT and Calar Alto telescopes of young stellar objects both in the Taurus and the Ophiuchus star forming regions. We report the discovery of 4 new binary systems: IW Tau and HK Tau/G2 in Taurus as well as GSS 35 and VSSG 14 in Ophiuchus; the projected separations are about 70 milliarcseconds (mas) for each of the Taurus objects, while for the Ophiuchus sources they are about 20 and 100 mas, respectively (20 mas correspond to 3 AU).
