Ultrasound gel alternative

Ivi • Baby #1 due in July 2018! Our miracle baby after almost 3 years of trying and 8 IUIs❤️❤️ My miracle was born July 8th, 2018! Motherhood is one of the most challenging, yet gratifying life change I’ve ever experienced!

I ordered a new bottle of ultrasound gel for my baby Doppler but in the mean time is there anything else I can use? Any suggestions ladies?
