There are many kinds of New Year gifts for such a big child. There are many kinds of baby products now. Let me recommend a few for you.
1. Children of four or five months old are particularly sensitive to toys with light and sound and like them very much. Children will definitely like the teddy bear toys that can emit colorful light. This plush toy can bring warmth to children and is a toy that can attract his attention.
2. Buy some clothes for babies. I recommend you a useful gift, such as a sleeping bag. Children are young and like to kick the quilt when they sleep at night. This is a trouble for many new mothers. It is better to give him a sleeping bag as a gift, which can prevent the baby from catching a cold and make the mother worry-free.
It is almost time to add complementary food to the four or five-month-old child. My sister's child can use a juicer to feed the baby some juice or fruit puree, vegetable porridge, etc. This kind of complementary food is the baby's favorite and is a practical and thoughtful gift.
