Re: not enough feedings during the day?
At that age, my girls nursed every 1-3 hours during the day and the night. They probably nursed about 10-12 times a day, minimum. And they had no schedule- at least, not one that I imposed. All their routines were self-generated.
While there are definitely some babies who can get all their needs met in just a few feedings per day, the average baby needs a minimum of 8 feedings per 24 hour period. I personally would not be comfortable letting a baby drop down to 5 feedings at just 3.5 months, so I'd take steps to change that pattern. I'd definitely offer the breast frequently during the daytime hours, even if the baby seems fairly uninterested. I think I'd aim to offer every 2-3 hours, or even more often if possible. At night, I'd make sure the baby slept in close proximity to me (so that I wouldn't miss her early hunger cues) and I'd reduce/eliminate my use of swaddling and pacis, since those 2 things can contribute to longer sleep stretches and less nursing.
