I just got this and I just had my third baby. When I opened it up for the first time my other two kids were so excited that they had to jump in and explore (4 years old and 2 years old). I bought it for my newborn to use as he grows and I wish I would have had it for my others as they grew too. Super easy to put up and down and great for the park, beach, or even just inside to keep the baby contained or away from the dog.
