When the baby was 5 months old, he began to be interested in the surrounding environment and began to try to explore with his hands. Here are some toys suitable for 5-month-old babies:

1. Soft dolls or animal dolls: These toys can make babies feel different touch and texture, and also provide comfort and security.

2. Colorful pop balls or rattles: These toys can attract your baby's attention and help them develop their visual and auditory abilities.

3. Plastic cups or containers: These toys can help babies learn to control their movements, such as pouring water or grabbing objects.

4. Baby fitness equipment: These toys can help the baby to exercise muscles and improve coordination, such as hand and foot crawlers and cushions.

It should be noted that when choosing toys for your baby, make sure that the toys have no small parts or sharp edges to avoid hurting your baby. In addition, toys should be cleaned and disinfected regularly to maintain hygiene and safety.
