Having dinner with another mom-friend this week has me a little insecure. My DD is 4 months old, her DD is 20 days older. She mentioned that she is using a jumperoo with her DD, and it was very clear that she was as the little girl was jumping in her dad's lap the whole dinner. I don't use a jumper and was more or less closed to the idea as I had read that jumpers/exersaucers/walkers hold baby by the crotch, encourage walking on toes and in the case of a jumper encourage baby to make a movement that they don't need to make (or something to that effect). When my DD stands in my lap, she stands very sturdily, no jumping or bouncing. Is this good, or should I encourage jumping, bouncing? My understanding is that the best place for a baby to be is on the floor on either tummy or back to help them build they strength that they need for each milestone... do you feel that these toys really help babies to meet their milestones earlier?
Also, this friend was introducing solids in the form of pureed foods, bananas etc. I had read that babies guts aren't really ready for foods until 6 months. I do cut up some broccoli, apples, etc and put them on the table for DD to grab and gnaw on while she sits in my lap while we eat so that she is in on the social activity (she was watching me put the fork in my mouth for each bite, so I figured she was ready to get in on the action in some way). The wikipedia article on baby led weaning (http://en.wikipedia.org/wiki/Baby-led_weaning) mentions mostly giving baby foods that the can grab and gum down on their own as opposed to pureed foods. I had never heard of this before, has anyone else used this method? What foods do you use?
