My son was the same way. He was nursing about every 2 to 2 1/2 hours until he was 5 months and I started him on solids. Breast milk does digest much faster than formula and I don't know anyone who uses the 3 hour schedules they talk about. It seems like you will never have your shirt down until solids are introduced! My daughter now is also a 2 hour nurser so I really feel like I don't have a break. She also uses me as her pacifier, which is tougher than knowing she is getting a meal. If that's what you think is going on try giving him the pacifier, a clean finger or his fist and see if he will be content with it. If he does seem hungry, don't let him not eat. As long as he is growing well, you know you are feeding him what he needs and that means you're doing an amazing job. Breastfreeding is tough. It takes a lot of work, so you are doing a great thing. As he gets older and more active he will want to spend more tme practicing his physical needs and not nurse as much. Also a growth spurt is very likely since he is about the right age, but those aren't always accurate lol. Mothering is so fun!
