Re: 3 Month old only calmed by nursing?
Don't worry- this is very normal and not a problem or a bad habit! First of all, it is completely natural for babies to be strongly attached to their moms. Back in caveman times, before the invention of strollers and cribs and bottles and silicone pacifiers, mamas carried their babies all the time and nursed them nearly non-stop. Seriously non-stop: studies done on "primitive" hunter-gatherer families found that babies naturally nurse as often as every 17 minutes!
Since the natural condition for a baby is to nurse frequently for comfort and for nutrition and to be strongly attached to mom, particularly in the early months, the real problem is our modern lives. We live in a society that expects mamas to frequently hand their babies off to dads, grandmas, daycares, and babysitters. But because a young baby's natural primary caregiver is a nursing mom, we shouldn't expect dads, grandmas, daycares, or babysitters to be able to comfort babies as quickly or as easily as we, the moms, can.
The good news is that this is all very temporary. A 3 month old baby is pretty much completely dependent on you. As far as she knows, you're still in caveman times and if you put her down she'll get eaten by a sabretooth tiger. But as time goes on she's going to become more independent. She'll get more interested in her environment and in the people around her, and that means she'll be less reliant on you. Now, the phases of intense mommy-attachment come and go- often as babies start crawling and walking they go through phases of separation anxiety- but it's all temporary, and the trend is towards increasing independence.
