Send letters every day. Include pages he/she can color, stickers, etc. Include pictures of yourself every so often. Do you see your child, at all? If so, do what your child likes. Maybe, that's coloring, cars, blocks. Whatever they like, get down on the ground and do that with them. Take them on walks and explore the outdoors. Getting outside and being in nature, is a great bonding experience. Find a children's book you like. Make sure you are the only person in your child's life that has that book. Read it to them when you see them. It will be something just the two of you have.
