My little baby is now 3 months and 2 weeks, since she was born I had to give her formula because when body didn’t produce milk for like 12 days because I had an infection

Then she continued on formula and sometimes she will have some breast milk but this is very occasionally 🥺

And now my body is producing a very minimal amount of milk 😔 I tried to pump but not regularly because when I see the amount of milk that’s produced I feel so disappointed 😔

Can my breast milk increase after 3 months ? Or it is too late and please give me tips to increase my milk supply for my baby 😔
