Welcome to YT.
There are so many threads for you to read through. I try to keep up and can't even come close! Just pick some random ones and start jumping in. Use the search option to look up info on particular questions you have. Then when you have a question you need some more help, opinions, or feedback on - just holler. Or pictures and funny stories are always winners too.
Oh, and wanted to add one more thing.... Your baby in your avatar is adorable!!
