Have a U shaped feeding cushion that has seen me well through the first 3 months of tandem feeding my babies. But now they are getting too long and their legs get all squashed against sofa back/bed head board and they have started to complain (not verbally, I hasten to add, but the odd grizzle!). Any suggestions on how I can continue to tandem feed, haven't got enough time to do one after another! Thanks.
