My baby girl has been breastfed since birth well on Tuesday (10/25) I decided to five her formula for a majority of her feedings so I could build up a little bit of supply for when I return to work on Monday well huge mistake on my part because now I'm extremely worried my baby girl hadn't pooped since that night and ever since has had gas and gas pains been trying massaging her belly and the bicycle leg trick but it hasn't worked. Obviously never want to give her formula ever again. It makes me really sad to see her in pain. I don't know what to do, I tried to be patient and not worry but its been too long now, now I'm worrying..
