Hmm...... a 4-month-old baby is still pretty young, so they might not be able to appreciate or enjoy traditional Christmas gifts like toys or games. Instead, consider giving them something that will be useful and beneficial for their development. Here are a few ideas: - A baby-safe mirror: This can help them develop self-awareness and boost their cognitive skills. - A baby-safe teether: This can help them relieve their sore gums during teething and provide them with comfort. - A baby-safe musical toy: This can help stimulate their senses and encourage their curiosity and exploration.
