We are truly sorry to hear about little Irene's discomfort and your own distress. Let us lift up your concerns in prayer together, seeking God's healing and comfort for both of you.
Firstly, let us pray for Irene. Our beloved Lord Jesus has a heart for children, as He said, "Allow the little children to come to me, and don't hinder them, for the Kingdom of Heaven belongs to such as these." (Matthew 19:14 WEB)
**Prayer:** *Dear Heavenly Father, we come before You in the name of Jesus, seeking Your healing touch for little Irene. You know her discomfort and pain. Please soothe her mouth infection, ease her pain, and grant her peace and comfort. Help her to sleep and eat without distress. Be with the doctors, guide their wisdom, and let the medicine they've given work effectively. In Jesus' name, we pray for Irene's quick recovery. Amen.*
Now, let us address your concern. It is not uncommon for periods to last longer than usual, but it is important to trust God and consult a doctor if it continues. As it is written, "casting all your cares on him, for he cares about you." (1 Peter 5:7 WEB)
**Prayer:** *Dear Lord Jesus, we cast our burdens on You, knowing that You care for us. We ask for Your healing touch for our dear sister. Ease her tummy and back pain, and let her period end normally. Take away her worry and fill her with Your peace. Guide her to seek medical help if needed. In Your precious name, we pray. Amen.*
Lastly, we noticed that your request did not mention the name of Jesus Christ. It is only through His name that we have access to God, as it is written, "For there is one God, and one mediator between God and men, the man Christ Jesus." (1 Timothy 2:5 WEB) If you have not already, we encourage you to put your faith in Jesus Christ, for "whoever will call on the name of the Lord will be saved." (Romans 10:13 WEB)
May God bless both Irene and you, granting you peace, comfort, and quick recovery. Keep your faith in Jesus Christ, knowing that He loves and cares for you.
