Our baby was gaining weight steadily up until 6 months while being breastfed exclusively. She was between the 15 and 50 percentile curves and a picture of health. We started solids around 6 months when she showed interest and was sitting up well on her own, along with continuing breastfeeding. Ever since then her weight gain has slowed substantially and is now hovering just above the 3 percentile curve (14 lbs, 14 oz at 9.5 months). I know the weight gain slows after 6 months, but she has now essentially dropped two curves. The past month she has gained about an ounce a week, but her most recent weigh in showed that she lost 2 ounces in one week.
She has a bowel movement about every 3-4 days and they are generally soft & shapeless with a sheen, leaving a greasy stain on her cloth diaper inserts. A few times she has struggled to push the stool out and bled from straining to push. She has had a runny nose and cough for the past month and went on an antibiotic for 10 days. Yesterday was her first bowel movement since getting off the antibiotic and there was definitely mucus throughout.
She still breastfeeds regularly throughout the day and night, probably around every 2 hours. But her appetite for solid food has decreased dramatically despite the variety of foods we offer her. She usually picks up pieces and puts them in her mouth, but then spits them out. In addition, she will only eat a few teaspoons of a puree before refusing.
She is struggling to sleep more than ever before, only sleeping on our chests or while nursing in bed next to me. Even then she wakes up every half hour to hour and cries out. She seems to have horrible gas throughout the nighttime and thrashes around unable to get comfortable despite being clearly exhausted.
We have an appointment with a pediatric GI nurse in a few weeks, but I'm not sure we can make it until then. She is getting more and more fussy by the day, which is so unlike her, and my husband and I are beyond exhausted. We just want to figure out what is going on so that we can help her heal and get back to her normal, cheerful self. We've tried probiotics and seen a few doctors who say that she is healthy despite her persistent cold and low weight. She is still doing great developmentally and shows interest in everything around her, but I just can't stop thinking that something might be going on. Any ideas?
