Might start to combo feed

I’m extremely fortunate that I’ve been able to EBF for about 4 months now. But the last few days baby has these moments where he just refuses the boob and I have to give him a bottle to settle him. It happened tonight (typing this at 3:25am) and I’m just tired. I don’t know if this is part of the 4 month regression? He’s been waking up every 2 hours to feed after previously being such a good night sleeper.

I know I shouldn’t feel this way, but I feel like I’m failing my baby in a way. I know formula is not a bad thing, my first son was 99% formula fed. But with this baby I wanted to breastfed for as long as I could. And I think I just hit the limit. 😞
