Welcome, songogga to you and your family! Qatar is very open to Christians practicing their religion as long as there's no proselytizing of Muslims. There are many churches here and I know you will find the right one for you and the kids. You might also want to find the mums and kids groups that meet here in Qatar and feel right at home from the start. There really isn't any problem with you being out and about with the kids, your husband certainly doesn't need to be with you. Novita's group and Expatwomanqatar.com can also help you with information.
