How often should your baby be having growth spurts? Mine is having growth spurt (I think, since become crazy hungry, need to feed every 30min) every other week, is this normal? Mummy daddies what are your experiences?

Agreed with Reine, if your baby needs to drink, just let him/her do so. Don't be stress as it will affect the supply. Just relax and enjoy the moment for the time being, and it won't be Long till Your baby will outgrown the routine when he/she starts solid food.
