Ok so my son is 6 week ummm Tuesday he had a BM at 6am kinda lite green he didn’t go yesterday but he did go early this morning around 4am

His Tuesday BM was like this but lite green. He is still his normal self no crying or looking uncomfortable. However he now has gas he started farting Tuesday. He still drinks all his milk 4oz every three hours and 5oz at 8pm(dinner) and 12am&4am if he wake up should I be concerned 🤔also I’m pumping he not on no formula

This is his milk in each jug it’s 2 days worth of milk which is gone within 3 days i suggestions
