At my son's 12 month check up, the ped told us that his weight has "plateaued" at 19.5 lbs. He's only in the 10th percentile for height & weight, so this was not good news. He still bf's 4-5 times, and eats 3 meals and a snack every day. He drinks diluted juice and water well from a cup, so the ped suggested giving him soy milk in his cup to boost his weight gain (he has a dairy allergy). I would like to begin weaning him soon, but right now I am just focused on getting him to drink the soy milk from his cup, especially because my milk supply seems to be dwindling.
Problem is, he absolutely refuses to drink it. He might take one sip if my husband offers it, but that's all. We've tried giving him a smaller meal/snack than usual or withholding other liquids to get him to drink the soy milk, but he just won't do it. We've tried regular, vanilla, different brands, different times of day -- nothing is working. He won't go near a bottle, regardless of what is in it, so that's not the answer either.
This has been going on for 2 weeks. Does anyone have any advice? I am getting really frustrated, which is probably making the situation worse, but I don't know what to do. Thank you!
