I've been using the Ergo 360 with insert since DS was about 3 weeks old. He has always cried a little bit once I've put him in there but has quickly settled and been happy in it (sleeping mainly). However, for the past 3 days, every time I've put him in there he has instantly started screaming (red face, sweaty screaming - not just a bit of crying) and will not calm down until I've taken him out or played white noise for 5-10 mins and he's fallen asleep. It's like he's in pain.
Has anyone experienced this? It's been working so well up until now and I simply can't use it if it causes him so much distress now
