Hey, I have a 2 week old newborn and his startle reflex is strong he struggles to sleep. I found the amazing tommee tippee swaddle sleeping bags and everything was going well. The health visitor came and said not to put his arms inside as he can overheat but didn't offer an alternative. Now he's waking all through the night when active sleeping and neither of us are getting much sleep at all. I'm already worried about him being too hot or cold and now I'm stuck. Room is a steady 18 degrees. Help, what layers can I dress him in/ swaddle him in, safely without the risk of him overheating? Thankyou- from one tired mum!
