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.
Infants and young children must ride in a child safety seat until they are 4 years old AND weigh at least 40 pounds. Every child ages 4-8 who is no longer in a car seat must use a booster seat until she reaches 4â9â tall.
