You can not feed it only bread with milk. Baby birds need different nutrients that are not in bread of milk. As gross as it sound, the best thing to feed it is, different insect mashed up. (No wings or hard shells. If you are going to feed it insects with wings, the wings must be removed first because they are hard to digest. Also obviously no bees or beetles. You can also feed it hard boiled egg yolks mix to a creamy texture with whole milk. Another good things to feed it if you don't wish to mash up insects is crushed up cat food mixed with water or milk. Milk is good to mix with because vitamin D is very important to them. You can use a medicine syringe to feed it. Baby birds generally need to eat every 20 Min's during the day and not through the night since the mother doesnt feed them at night. I hope this helps...
