Aiyoh don't worry lah, sikit je makan mana boleh jadi apa, kalau serious sangat doc would say completely avoid, bukan sikit-sikit boleh jadi masalah, so I think you're okay! But honestly since you're still in early recovery and also advanced maternal age (congrats on your baby after 5 years TTC!), best to check with your gynae just to put your mind at ease, especially since postpartum period ni sensitive.
