My baby chokes every time my milk lets down. I have tried different holds and positions but it still happens. He is swallowing excessive air as a result and having terrible stomach pains. I was told that pumping prior to nursing until after let down is achieved would help but I have not been able to hand express for that to happen and do not own a pump. Also, the baby is still nursing quite frequently, sometimes every 20-30 minutes which doesn't really leave me much time to pump at all. Also, if he has to wait even a minute to nurse from first giving his "signs" that he's hungry, he becomes very aggresive when latching on. Is pumping a good idea in this scenario? Any other suggestions are greatly appreciated as well. Thank you in advance!
