We are all fathers and brothers and sons. Your pain is our pain. After you make the hard choices, your wife will need you. That can be a beautiful time to come together.
You will need the healing that only God can give. Friends and family will help, but God is always there to provide comfort.
It takes a solid year to work through grief and loss. Don't be captive to it, but accept the loss and help others through it, especially your wife. Helping others does make it a little better.
Nothing will replace your love and that love was mutually felt. Glory in those happy moments and the joy that you shared together with that precious child. My prayer is that God's compassion will shower upon you and your wife.
You always have friends here. Don't be a stranger.
