I also let my daughter eat S26 but she discharge so infrequent, 4-5 days once and even 11 days!I'm afraid too "hot" and then change to A+, but didn't work. BB still discharge once per week!! Finally change to 森永 last 2 weeks and BB discharge every other day or even everyday! If I know it earlier, I will change earlier! and also she didn't 多"屁" as before. You may try it!
