DD2 definitely has some intolerances and we're trying to work out what they are at the moment. HV is very reluctant for me to start messing too much with my diet and prefers the wait-it-out approach. I've been off dairy since Christmas and we saw some improvement in her.
She has reflux and is on ranitidine, but does tend to spit it out. However, it does seem to help her too. We've had more calm moments with her since she started it a week ago. However, there is something which is setting her gut off. She produces loads and loads of wind which builds over 24 hours and leaves her in excruciating pain. I spent most of yesterday with her nappy off trying to get rid of it with tummy massage and leg movements and bathing her as she calms down for this. Her reflux worsens during these episodes. She doesn't sleep even though she's knackered. Something wakes her up within 15 minutes of falling asleep (usually 5 mins) and that is her up again for a while. She falls asleep at the breast so deeply that she doesn't burp, so when she does wake she is really windy and winding her upsets her even more and produces more reflux. Her nappies are expulsive and mucusy.
Her big sister was sensitive to gluten. I'm willing to try that again, but it is a big undertaking to be dairy and gluten free (not to mention expensive) so I wondered if anyone had had these symptoms in their LOs and narrowed it down to something else. I've tried a food diary, but I find it all so wooly that it's hard to interpret (e.g. I have gluten every day, but her episodes tend to be a day and a half after eating pasta, but then I have tomatoes and garlic at the same time so it could be them? But it may be something I ate since that too.) The other suspect might be nuts as I crave them for protein instead of dairy at the moment. But I have them every day and she tends to flare up for 24 hours, calm down gradually over the next 2 days and then be OK for a day or two.
