You may want to rethink the idea of giving your daughter everything. That only leads to spoiling your child and not allowing her to take pride in saving and making her own way in life. If you want to build up a little extra as a buffer why don't you stay with your mother-in-law longer and save up the extra before moving out. Her reasons for saying no may be valid for her. If she gives to you now, most likely, you will expect it again. Try to live within your own means and be thankful she is gracious to allow you to stay.
