I just realized this was from a long time ago. I am new to mamasource LOL. Anyway if this were going to get to you back then this is what I would have said.
Hi N., I am a mom of two boys also breastfed. I know a ton about breastfeeding and so forth so I would be happy to help you. You should be able to start again if you want to. It sounds like you have twins?
The bottom line for me is that I have to get some time for myself too but breastfeeding has been much easier than bottle feeding would be. Cereal is not recommended as a good food choice for babies, it is basically nothing but sugar. It's a refined grain. So I would ditch it. The best solids for babies that age are fruits and veggies or even meat. I usually introduce easy things that do not need to be jarred, like bananas and avocadoes first. Even strawberries. But 7 months is pretty young and they really do not have to have solids if they are not reacting well to them.
They probably are teething, which makes them fussy. Since there is no local Frisco LLL I have gone to the La Leche League of McKinney in the past. They have a yahoo group called ____@____.com You could try to join and see what happens. Or send me your email and I will make sure you get an invitation from one of the leaders.
By the way if they are having formula too it might also be the formula causing fussiness. But sometimes babies do that during a growth spurt. Kudos to you for breastfeeding for the first 6-7 months which is definitely great for those little babies!!
Oh yeah also there is www.promom.org
