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.
Typically, newborns are able to reach this milestone around 3-4 months. For the parents that we asked, 4 to 6 months is the typical age they start using the jumperoo for their baby to play. There are many different variety of jumperoos from companies like Fisher Price, Baby Einstein, EvenFlo and Bright Starts.
