registering you can do whenever you want, just make sure to keep your registry updated, as things may go out of stock.
kicking you may not recognize until later. it may feel gassy, or fluttery, or like i real kick, only much softer. i had that with my fifrst one really early, can you imagine???? i was feeling things at 13-14 weeks, and ppl told me im nuts, and i would say i know i am, but i still know what i felt.
about the child care, i wouldnt start looking till closer to the end of the school year. by the way, i heard theres a new baby sitter in your neighborhood who is REALLY inexpensive!! you should check her out. as far as i know she doesnt have any other kids yet.
