Is it normal for my baby to have so much difficulty latching?

Yes. Remember, that breast feeding isnt an easy thing to just pick up and be anexpert at, for you or your baby. For both of you, it will take plenty of time to get comfortable and become very good at it. Just keep practicing and very soon, both you and your baby will be an expert. If you are having a more difficult time still at 5-6 days, call your doctor or a lactation specialist.
Yes. Yes, it is normal. Every baby is different. Breastfeeding is a wonderful experience for both mother and baby. However, it does not always occur as naturally as we hope. It is normal for latching difficulties to occur initially. It is always a good idea to have a lactation consult to discuss the specific needs of each mother-baby connection. Correcting latching issues will result in a happier baby.
