I am planning to travel to Nepal is there something helpful that we can bring along with us?

One thing that is helpful to bring is quality reference books, for example (recent) encyclopedias, general information books that can be used in school libraries especially for the higher age groups - most books in the schools were totally destroyed. It is generally not helpful to bring clothing items as clothing can be obtained cheaply here, but leaving your own unwanted fleeces after your trekking can be help. Medical supplies/first aid items can also be helpful, providing they are not out of date items. Second hand laptops in good quality condition would be fantastic, as are good quality second-hand smart phones – developing communication hubs and helping the schools restart their computer classes is important. But please make sure they're in good condition, ones with broken pieces, no longer working batteries are really not very helpful and a burden. Oh and photos/mementos of your own country/family to leave as gifts means that you will be leaving a part of yourself in Nepal to be remembered too!
