There is a great indoor playground not far from us especially for your younger child. It is located off of Aloma and my 3 year old loves it when we go there. It is a gated play area with several stations throughout the play space. There are houses to play in, train table, garden, indoor play set, and even a section just for the youngest kiddos with tummy time areas. There is also a nursing area with quiet and seating. Everyday they have a story time which is included in your price to enter. At story time they do a few songs and a couple of books. It is a really relaxing environment and they even have Yuck buckets to put any toys that your little one put in their mouth. They also have an area in the back where you can eat snack or even lunch. There is also a fridge if needed.
Their prices are
Infants 0-3 free
4 months-11 months $6+tax
1 year-5 years $10+tax
Don't forget your socks not just for your little one but for you too.
