A study shows that  ability because bigger blocks easier expert hand movement new nowadays physical properly researchers strength study technology things time underlying way    technology is reducing children's  ability because bigger blocks easier expert hand movement new nowadays physical properly researchers strength study technology things time underlying way    to use a pencil or pen. The  ability because bigger blocks easier expert hand movement new nowadays physical properly researchers strength study technology things time underlying way    is from the National Health Service in the UK. Researchers said that  ability because bigger blocks easier expert hand movement new nowadays physical properly researchers strength study technology things time underlying way   , children spend so much  ability because bigger blocks easier expert hand movement new nowadays physical properly researchers strength study technology things time underlying way    swiping iPads or mobile phone screens that they cannot hold a pencil  ability because bigger blocks easier expert hand movement new nowadays physical properly researchers strength study technology things time underlying way   . Children are not using pencils, so they now lack the muscle  ability because bigger blocks easier expert hand movement new nowadays physical properly researchers strength study technology things time underlying way    in their hands to be able to write properly. Researcher Dr Sally Payne said: "Children are not coming into school with the  ability because bigger blocks easier expert hand movement new nowadays physical properly researchers strength study technology things time underlying way    strength and [ability] they had 10 years ago. Children coming into school are being given a pencil but are increasingly not able to hold it  ability because bigger blocks easier expert hand movement new nowadays physical properly researchers strength study technology things time underlying way    they don't have the fundamental  ability because bigger blocks easier expert hand movement new nowadays physical properly researchers strength study technology things time underlying way    skills." The  ability because bigger blocks easier expert hand movement new nowadays physical properly researchers strength study technology things time underlying way    said technology is changing the physical  ability because bigger blocks easier expert hand movement new nowadays physical properly researchers strength study technology things time underlying way    that children write, draw or make  ability because bigger blocks easier expert hand movement new nowadays physical properly researchers strength study technology things time underlying way   . Children are increasingly using  ability because bigger blocks easier expert hand movement new nowadays physical properly researchers strength study technology things time underlying way    to create. Dr Payne explained why. She said: "It's  ability because bigger blocks easier expert hand movement new nowadays physical properly researchers strength study technology things time underlying way    to give a child an iPad than encourage them to do muscle-building play such as building  ability because bigger blocks easier expert hand movement new nowadays physical properly researchers strength study technology things time underlying way   , cutting and sticking, or pulling toys and ropes. Because of this, they're not developing the  ability because bigger blocks easier expert hand movement new nowadays physical properly researchers strength study technology things time underlying way    foundation skills they need to grip and hold a pencil." Some experts say technology may be causing  ability because bigger blocks easier expert hand movement new nowadays physical properly researchers strength study technology things time underlying way    problems. One  ability because bigger blocks easier expert hand movement new nowadays physical properly researchers strength study technology things time underlying way    said if a child isn't strong enough to hold a pencil, perhaps their whole body is weak. She said it was better for children's  ability because bigger blocks easier expert hand movement new nowadays physical properly researchers strength study technology things time underlying way    development to climb trees than to watch YouTube videos.
