The easiest way to ensure you end up with a mild jalapeno for these poppers, is to remove the ribs and seeds - that's what holds most of the heat of a jalapeno. Baking the peppers with that cheesy bacon filling is also going to help them mellow out a bit. If you like a bit of spice, try adding some of the seeds back in to the cream cheese filling and you'll get a bit of heat in each bite!
