Hi blueberrysmom! I'm glad you've gotten some encouragement here and are feeling better.
I have a question (that may have been answered somewhere in the thread; sorry if I missed it!)... Did you say that your baby's last "official" weigh-in was at 2 months? Has she not had a doctor appt since then, or does your ped not do a weight check at each visit?
I'm just thinking that having that professional evaluation of how your baby's growth and development is going would probably be reassuring.
About how often your baby should be nursing -- here's an
article about the "Magic Number", which is the number of times per day a mom needs to nurse in order to keep her milk production steady. Basically, it depends on the storage capacity of the mother's breasts, and is different for every mom. A mom with a small storage capacity is going to need to nurse more often than a mom with a large storage capacity.
I remember my sister-in-law talking about how her babies nursed every 4 hours at 6 months old and I was shocked. Neither of mine ever went that long. Ever! They both nursed at least every 2 hours during the day and several times at night for the entire first year. My DS was nursing 10+ times per day at 13 months. Now I realize it's because my SIL had a much, much larger storage capacity than I did (I don't think I had
any!).
So anything that describes a "normal" pattern for how often babies should nurse is going to be wrong for 95% of the population. What's actually normal is going to be something different for every mom and baby pair.
