Baby is 5 months soon and was doing 8-10 hour stretches of sleep at night but is now up every 3/4 hours for a feed. She shows interest in food and opens her mouth and follows the food when we are eating, as well as being able to sit up for a little while at a time. Do you think we should start introducing food at this stage? She also has reflux so don’t know how she will do with food.
