There are some corrections that need to be made for better comprehension, but overall your meaning is clear. Every Sunday we go to church. I haven't had my son baptized yet, because I am waiting for my sister to come with us to the ceremony. I want her to be a godmother for my son. Every Sunday when we go to church my son sleeps during the service in my hands. Like my daughter, he refuses to sleep in his cot or in a stroller when we go out somewhere. I hope that this helps :)

From what i understand from your statement, i had made some corrections on it: Every Sunday we go to church. I haven't had my son baptidized yet as I am waiting for my sister come to find us . I want her to babysit my son. Every Sunday go to church, my son is sleeping on my hand during the service. He just likes my daughter which refuses to sleep in his cot or baby stroller when we go out.
