Its funny I used to be right in the middle of social butterfly and social hermit.
I have an outgoing personality so I spent many years in outside sales. I also worked retail in high school and part of college and enjoyed being around people. BUT then in my down time, I needed my own space to be alone and not have to talk to anyone or be with anyone.
Now that I'm a sahm with a daughter who also is very social, but also likes her space sometimes, I could fill my calendar with an activity a day if wanted to. Some weeks I am very happy being at home and doing stuff here, but other days, I really like that interaction with other people. Usually people who share a common interest whether scrapbooking, breastfeeding, coffee clubs etc.
So when I first went to meetings for LLL, dd was 3 mos old and another mom wanted to go- so I went as her "chaperone" so she would not be alone. But I did like the social interaction, talking with moms who also were breastfeeding and it made me comfortable knowing that I am not the only mama who may have spent the entire day before nursing my growing babe and no there was nothing wrong with my baby...
Most meeting I have attended, you have the subject at hand for discussion, like Darlll said, but in my experience, that is to keep things going. If someone has another question, that would be covered. If the subject said dosen't really need to be addressed for whatever reason, we cover what other questions are.
an example- the topic is nutrition and weaning. Well a new mama walks in almost in tears and we find out during introductions that she is almost in tears because she is having trouble with sore nipples and baby not thriving according to her sources. Now for a leader to brush that off and get to the topic, that mama would learn nothing and feel like a failure to boot. So she can start asking questions and other mamas might say "that happened to me....." Then we find out, she is holding the baby wrong, and no the new baby has gained weight and is getting 8-10 diapers a day blah blah blah. Then we can tie the subject together talking about nutrition for this mama and then passing it on to the baby. Then move onto talking about weaning the other topic. In the meantime, this original mama can relax, nurse and learn something and then ask questions of the leader and other mamas around here. An example I have seen a few times I might add.
If there are no other questions about the topic to be covered or any other, they call the meeting closed and usually then the topics are amoungst the moms in attendance. At the last meeting, this social time where people are either getting ready to leave, gather their toddlers etc a mother asked about starting solids to the other moms and we could talk about it. Another wanted to talk about cloth diapers to a cding mom of 2.
So you may not make all your new best friends at the meeting, you may not like anyone. But its a fountain of knowledge for more than just brestfeeding.
In all the meetings I have attended, I have only seen one person complain about the meeting. It was an expectant mom who said- I thought we would talk about nurtrition and weaning!!! Why she needed to know that right away, no clue. Maybe she thought it would be a lecture series or something instead of a bunch of nursing moms in a circle with a mess of toddlers, some nurslings themselves.
