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.
A lot of the time, these mothers experiences will save you a lot of time. --now to the original question... My son just turned 5 months and I put him in both a bouncer: fisher price jumperoo (when he was 4 1/2 and a walker).He loves the bouncer, and he just learned how to move in the walker 3 days ago. He can already roll over on his own and hold himself up with assistance.here should be no objects or furniture that are at the child's head/body level and which the child with a walker can fit under. (i.e. like a table edge may hit baby's head or body while baby and walker are going under it.) Remove such protruding objects or do not let baby roam in a walker in that room.
