i dont have a specific rec., but just wanted to give maybe a dif. pespective...
it really depends on the child, with my younger kids they had little interest in playing in anything confining-walkers,play pen,swing etc. they just would climb out or want to get out and play with/follow older siblings. i'm not against it. we had swings etc too, but especially since theres such a limited time to use most of them i really support buying used in good condition. and just try not to worry about getting the coolest and so on. also, if you decide not to get something for the baby to play in, thats fine too. thats what they do in daycare giving as much 'tummy time' as possible so they can practice crawling,standing so on and learning from her big brothers.would need a gate or obstacle to block some areas.
on the other side of the issue,some infants really love bouncing,swinging. doing anything to make legs stronger is always good. its just something to think about. and she's so lucky to have her brothers to help and teach her. congradulations, and try to enjoy those growing up moments. anytime you have a question, lots of moms on here to support you or give tips. i know sometimes being a mom is really frustrating, so if you needed to vent you could do that too. good luck in finding the right equip. and getting some sleep.
