Here are some of tricks that I've used and have worked more or less.
For the fever:
- Remove some layers of clothes, sometimes to the bare minimum (only the nappy)
- A warm bath (slightly colder than the usual)
- Calpol (Seriously considering buying some Stock shares of this company)
- Lots of liquid (colder than usual milk, water, diluted juice, etc.)
For the congested nose:
- An onion cut in pieces so it "bleeds" next to his/her head.
- Put some books under the top end of the cot and tilt it so the baby's head in higher than the feet.
- Saline drops (Some babies hate it, some babies love it, but it works)
- Some container with water over the radiator for having some steam in the room.
- Snuggle baby ointment (for the chest, the back and the neck)
In general:
- Try to make turns with your partner for calming the baby down. It will be a long night.
- Make sure you are wearing warm clothes when you attend the baby: the steam and the fever will make you sweat and get cold yourself!!!
- Patience, lots of it. You will get annoyed and sleepless for a few nights, but it gets better. Promise.
