The signing of each page of a will, or the initialing of each page, is something which is done through excessive caution, and is not a legal requirement. The decedent's signature is, however, a definite requirement, but it need not be "fancy handwriting". If the decedent were physically unable to sign, she could direct someone else to sign for her. Two adult witnesses must have observed the will signing, and they must also sign the document. It appears that the legal issue, if there is any, may not relate so much to the signing of the will, but to the issue of whether your grandmother knew what she was doing, and that she did it voluntarily.
Per the MN state website:
Wills can be changed either by writing and executing a new one or by adding a “codicil,” which is an amendment to a will. The codicil must be written, signed and witnessed the same way as the will, and should be kept with the original will.
My answer is not intended to be giving legal advice and this topic can be a complex area where the advice of a licensed attorney in your State should be obtained.
Hello. I am sorry for the loss of your grandmother. This website is not providing legal advice and only provides general information: Assuming you have a substantive concern, you should immediately seek private legal counsel, because likely the facts and issues that need to be explored go far beyond those you stated. There is no rule that a person has to remain alive a certain length of time after signing her/his will in order for the will to be valid. A person's signature often varies over time, and varies due to the physical and other circumstances of the signing. If you reside in a remote area, you may contact any Minnesota licensed attorney, as some attorneys will make special arrangements to provide legal help to you. Some attorneys are available seven days for emergency legal needs. Many attorneys will confer initially at no charge. Then, if legal work is performed, some attorneys will provide a reduced fee for financial hardship. Some attorneys may also assist you in limited scope manner to conserve legal costs. All the best.

I'm very sorry for your loss. As noted by Attorney Dwyer, it is vitally important that you retain an experienced attorney as soon as possible to review this matter. Good luck to you.
