You can use an if statement to check whether i is smaller than 11:

$(document).ready(function() {
  var inputs = $('.product-options').length;
  var max_inputs = 15;
  var i = inputs;
  var number = inputs;
  if (inputs < 2) {
    $('.add_field_button').click(function(e) {
      e.preventDefault();
      number++
      i++;
      if (i < 11) {
        $('.form-product').append('<span  id="row' + i + '" class="myinput" style="transition:1s ease;"><div class="form-group"> <div class="col-sm-7">  <input type="text" class="form-control product-options" name="childen' + number + '"' + 'value="" placeholder="the option"></div><div class="col-sm-3"> <input type="text" class="form-control product-options" name="childprice' + number + '"' + 'value="" placeholder="option price"></div>  </div> <div class="form-group"> <div class="col-sm-7">  <input type="text" class="form-control product-options" name="childsrb' + number + '"' + 'value="" placeholder="the option in serbian"></div><button type="button" name="remove" id="' + i + '" class="btn btn-danger btn_remove"><i class="fas fa-times"></i></button></div></span>');
      }
    });
  }

  $(document).on('click', '.btn_remove', function() {
    var button_id = $(this).attr("id");
    $('#row' + button_id + '').remove();
    number--
    i--;
  });
});
