Re: 3 week old with tonge-tie
My son was tongue tied and was clipped at almost a week old. It took him another 2 weeks to latch. The procedure wasn't horrible but like anything with your newborn breaks your heart a little.
As for pumping, you really need to increase the amount or it will be harder later. You should pump whenever he eats, however that may be. Formula or breastmilk. Because once your baby is ready, willing and able you don't want a low supply to frustrate him and increase your problems. It's such a short time in his life. I really encourage you to stick with the pumping. It's worth it, trust me.
