Ohhh, hang in there. Just DO it. Don't go anywhere special, but just start GOING. Do simple. To the store. To the park. Just for a ride around the corner if need be. Getting out is so important for your sanity.
WIth my first ds, I had similar issues, he puked, bad latch, HUGE boobs, etc etc yada yada and then when we did go out, I was so nervous he would scream the entire time (plus he was high needs anyway). Once I got comfortable with nursing, it was easier (at about 6 months) but by then it was WINTER ROFL
Now my dd is almost 4 months old, and as an example, we left the house yesterday at 10 am. I nursed her before I left. Took double jogger and walked to post office. Then to bank. Then right on to a birthday party where we were there for 2 hours. Had a little pass the baby, and then held her the rest of the time (and I might add, all the other babies were in their little buckets the ENTIRE time while Reilly got to be part of the festivities. LOL) I nursed dd at the party. Party over, walked home. Got home, baby never went inside, she was napping in stroller. I ran in to pee, get ds a snack. Back out, ds ate a picnic lunch on the lawn while I mulched the front of the house. DD woke up from nap in stroller, I changed her diaper, nursed her on the lawn, laid her on the lawn on blanket for some tummy time. After awhile, we went to play across the street with friends. Played pass the baby for ahwile. (I live in a GREAT neighborhood, makes my life blissful) Back in at 6:30 pm
so she was out from 10 am to 6:30 pm straight and never was inside once during that time. She napped in the stroller, on my shoulder, on my friends lap, and in the sling. Now that is not typical of my life so far, usually we are at home all day (but outside for a good part of the day but in our yard or out front with neighbors) and I will put her inside for her naps but I nurse her outside on lawns or porches, even in my car in the driveway if I need somewhere to sit LOL and do an errand or two once or twice a week, and get out somewhere EVERY DAY in the stroller if its not raining. If it rains, I stay home. But I HAVE to, because I have ds and can't keep him in all day. So we are adapting.
My days are mostly outside, either at my own home or the homes of my neighbors. I go to the park, to the grocery store, dry cleaners, or for pizza with ds. I go to Starbucks and to the library. I don't do road trips far because she doesn't like the car, and I don't do things to get my 3 year old riled up because then I have to worry about 2 of them. The mall is OUT for my ds, but its a great "first time" trip. My dd is like a pocketbook that nurses. That is how I describe her. Its funny with ds I was always planning things around him. NOw with dd, I can't do that, so she just has to come along. BUT she has the temperment for it. She goes 2-3 hours betwee nursing and is a quick nurser with an awesome latch. I also nursed ds for 2 years and have absolutely no compunction about whipping my boob out whenever and nursing her. I'll sit right down on the sidewalk if need be.
Anwyay, moral of the story is, practice makes perfect. Get out for fresh air. You can't work the kinks out until you know where they are. ANd go places that have lots of benches ROFL.
