Drop in supply! HELP!

Ma

So I'm in Tx and we had that big (for us) winter storm last week. Due to my job I had to stay at work for 6 days straight. My 5mo stayed with my in laws because my husband also had to work. Long story short I was not able to pump as often as needed to maintain my supply while away from my baby.

Last night he was so fussy and spent almost the entire night on my boobs. After I left for work my husband gave him a formula bottle that he gulped down and finally went to sleep. 😭 I feel so bad that he was hungry and I was too tired to realize it.

Anyway. The point of this post is to ask for advice on how to increase supply relatively quickly. If I feel I am still having a supply issue when he turns 6 months I'm tempted to switch to 100% formula.
