Water for Baby?

I’m a FTM and have read so many views about when to introduce water to your baby. He’s BF but drinks from a bottle when I’m at work. At 5 months old, I’m worried if I don’t introduce water soon he won’t have anything to do it later. When's the right time?

Time to wean?

My baby is 8 months old and still gets up at least twice a night to nurse. He doesn’t seem to drink much and falls back asleep quickly. Unfortunately, I’m not getting much sleep and having trouble keeping my eyes open in the afternoon. His weight is normal and he’s healthy otherwise. Should I keep letting him nurse? If not, what can I do?
