Co sleeping toddler and pregnant

Can anyone help me! I have a nearly 3 year old who sleeps with me and his daddy every night but I'm nearly 19 weeks pregnant and he's been kicking in his sleep and kicking my bump! I need him to stay with us until the weather gets warmer as we live in a very old flat and the heating isn't enough to keep him warm in the night how can I keep him with us and warm but also protect bump xx
