Baby weight check. Normal? is it normal?

Our baby is 30 days old . Her birth weight is 2.645kg , later it got reduced to 2.4 after a day or two Then she has come to 2.6kgs in 1-2 weeks Now her weight is 2.755kgs She pee almost 5-6 times a day and poop several times which is yellowish ( with like seeds sometimes) She gets breastfed almost 10-12 times in a day , as in when she is hungry she cries and gets her milk Sometimes when the baby cries or grunt and turns pinky, we substituted with formula milk but not more than one time in a day Addition to it, we give well baby drops and zincovit of 0.5 drops in morning and night respectively. My questions are 1. Current weight is normal? As people saying it's something to be worried . 2. Baby cries a lot during peeing, pooping and releasing gas.. is it normal ? Note: her mom ( my wife) having normal food ( no restrictions as such), she eats garlic , shallots, drumstick, carrot, snake guard, broad beans along with spinach, sweet potato, little bit of potato ( only few times)
