13 week old dd is breastfed, had a posterior tongue tie snip a week ago, is having gaviscon however the reflux remains. She screams a lot like she's in pain from either the reflux or wind. She hates lying down but will also eventually cry when being held upright so she ends up crying herself to sleep as she is exhausted but wake after half an hour. She won't go in a sling, I've tried 3 different ones, she hates the car seat and car, she cries in the pram. She hates lying on her tummy. We have a wedge for playtime, she tolerates a swing for 5 minutes. She will puke about 5 times and then the crying begins. We are waiting for an appointment with paediatrician but it's not until july. I am at my wits end as I can't stand to see her in pain and also it's really affecting ds 2.5 as he gets quite upset when dd cries. She is fine weight wise. Is there anything else I could possibly try or will I just have to wait it out? We are all so miserable, if it wasn't for the fact that ds needs to go to groups I don't think we'd leave the house!
