Kitted out in a padded down jacket, jumper, scarf and goretex boots, I still felt the biting cold. Around me young children, their faces red and raw from the low temperatures, played around. Most didn't have proper shoes but ran around barefoot wearing plastic slippers.
This region has seen its coldest winter in 20 years. Earlier this month, Lebanon and Jordan faced severe winter storms and heavy snow. It was an especially miserable time for the refugees, many of whom fled with just the clothes they were wearing. Large numbers are living in tents, damp unfinished buildings, or makeshift self-built shelters without heating or electricity. In Zataari, many tents collapsed or flooded in the heavy storms.
Oxfam and other agencies have been providing warm blankets, mattresses, heating oil and stoves to try to provide some relief during this difficult time of the year.
Parents complained their children were getting sick - coming down with colds and bronchial infections.
The children still played outdoors - seemingly resilient to the horrors many had witnessed back home. But watching some youngsters in one neighbourhood sheltering refugees in Lebanon, playing mock war-games with sticks and hiding behind building blocks to escape mock sniper fire, I realised that the scars of conflict will take a long time to heal.
Five year old Mahdi, a sweet-faced boy with twinkling eyes, has very real scars that his family showed to me. He was shot at by a sniper. Miraculously, the bullets exited his back, leaving ugly scars but no other serious physical damage.
Children like Mahdi need more support than they're getting now - not just now but probably for a long time to come.
The UN and aid agencies have been struggling with big funding shortalls, hampering their ability to provide the scale of aid that's needed to respond to what's become a massive flow of refugees - more than 700,000 at the latest count. In the past month alone, more than 40,000 Syrians have crossed the border seeking safety in Jordan.
Today's promises of large-scale aid are encouraging. But promises and pledges must be quickly turned into real aid on the ground so that families quickly get the help they so desperately need.
