The soft spot, known as the fontanelle, on a baby's head typically begins to harden between 9 to 18 months of age. The anterior fontanelle, located at the top of the head, usually closes by around 18 months, while the smaller posterior fontanelle at the back often closes much earlier, generally by 2 to 3 months. This process allows the skull to grow and protect the developing brain while accommodating delivery through the birth canal. Regular pediatric check-ups monitor the closure of these soft spots to ensure healthy growth.
When first born, it is normal for the top of a puppy's head to be soft. This is called the soft spot or fontanelle and is where the bones of the skull have not yet fused to facilitate the birthing process. Over the next few weeks the soft spot should harden and fuse.

To harden soft wood effectively, you can use a wood hardener product that penetrates the wood fibers and strengthens them. Apply the wood hardener according to the manufacturer's instructions, allow it to dry completely, and then sand the surface for a smooth finish. This process will help increase the durability and hardness of the soft wood.
