Yes, hydrogen would be an excellent substitute for helium to fill balloons for a kids birthday party as hydrogen is lighter than air and can provide plenty of lift. In addition, hydrogen is much safer than helium as it is not flammable and does not have any toxicity issues. Furthermore, hydrogen is much easier and cheaper to obtain compared to helium.
