How to wake for a feeding?

Ta
Do you ladies wake baby up to feed them? Or just let them wake up by themselves? My baby is 48 hrs old and I'm only breastfeeding for now. She sleeps and wakes herself up showing me ques that she's wants some boob. But when I pick her up, she latches, takes like 2-3 sucks and then falls asleep again. Any suggestions. Please don't bash, FTM TIA.
