Making the switch. Any tips? Help please!

I

My son is 2 months old. I have been trying to make the switch from the breast, to bottle/formula because I am no longer producing as much as I used to, & I will be starting work soon.

I’ve tried 2 different bottles, I’ve tried playing with the temperature of the formula/bottle nipple, I’ve even tried tricking him. He’ll suck for about 30 secs or so, & then stop.

Any suggestions? Please help, I am starting to get desperate 😩

If it helps any, I am giving him Similac(blue can).
