When dealing with a headache, try boiling one cup of apple cider vinegar and one cup of water in a pot. Pour into a heat proof bowl and put on the table or other safe place that you can lean over the bowl and cover your head with a towel. Inhale the steam for a few minutes to bring some relief.
The warning on mine says not to use prior to 4 months of age. My son was in his Jolly Jumper from 3 months. The directions of use are that if they can confidently hold up their head then they are fine.
3. Booster Seats. Once a child reaches 4 years of age and weighs at least 40 pounds, she can move to a booster seat. A child is required by law to use the booster seat until she is 8 years old or 4â9â tall. Both backless and high back booster seats are available.
