My little boy has a cold too. He can’t sleep on his back because of it and only really settles lying on our chests. At my 10 day appointment the midwife said to go to the GP if he gets a temperature but otherwise to let it pass.
Little remedies saline spray! 2 sprays in each nostril + nose aspirator after deff helps the breathing
My little boy currently has the cold I took him to the drs and he wasn’t concerned at all. Only way he would be concerned is if he wasn’t drinking, no dirty nappies and his breathing was terrible x.
