DS is just about 8 months old and we have been introducing solids over the last couple of weeks. He really hasn't been into it until now so I have just been following his lead and not really stressing about it. He barely eats anything at all - no more than a teaspoon in a day but somehow has become awfully constipated. It has been 5 days so far and I can tell he is really uncomfortable (he normally goes every other day). He is exclusively BF otherwise and I have been giving him some pureed pears the last two days in hopes that this would help things along...but still nothing and his gas smells absolutely awful! Poor little guy. Any advice? At what point should I take him to the doctor? How long is it safe to let him go without pooping??
