Going on holiday next month and have picked up a second hand yo-yo to take with us. Baby will have just turned 5 months old, is around 50% centile, born at 39 weeks. Do I need to invest in the newborn pack/bassinet? She currently is in the rumble seat of our uppababy but parent facing and in an infant insert within it. It just seems like an expensive purchase for a week, but I don't want to compromise her safety by putting her in the stroller too early.
