Falling asleep while breastfeeding

& I'm not talking about the baby!

How do I keep myself awake while baby is feeding?!

I have the hardest time with early night time feeds if I haven't been asleep that long (at least an hour or so). Other times, I can stay awake more easily. I feel guilty for not paying full attention to her & worry that she's not getting the most from me because of it.

Just for a little info, baby girl is 1 month old. She feeds every 2 hours during the day and every 3-4 hours in the evenings & at night.
