This nursing pillow is a great alternative to the boppy pillow. The extra seating accessory is great for wiggly babies. The item can be purchased at walmart for $20 compared to the $50.00 for the boppy pillow. You should consider purchasing two: one for the traveling and another for home.

Baby #2 is on her way !! hooray!! As I sort through all of the baby items I have from my first child, this nursing pillow is definitely staying. For me, my son never need the seating accessory but maybe baby #2 will will need it. Overall definitely $20 well spent. I have purchased a lot of baby items over the last two years and I can honestly say this had been on of the best!
