The Moro reflex (also known as the startle reflex), one of the eight reflexes your baby was born with, is the one reflex that most parents want to limit as much as possible. Causing your baby to fling out his arms, extend his fingers and legs and then to retract them quickly, the startle reflex occurs in response to loud noise or sudden unexpected movement. And it can cause your baby to cry, as his own sudden movement seems to have an unsettling effect.
Startling can also occur when small movement are made - like those during sleep - and, as a result, it's possible that your baby may wake himself by startling. If this is a common problem for you, you may want to consider wrapping your baby, as a wrap will restrict his movement and so limit the extent of startling that can occur.

The hottest of hot topics for many parents is getting your baby to sleep. At Week Three, you and your baby will probably be a long way from anything resembling a routine. And this is as it should be, although probably not what you want to hear!
Most babies this age will sleep for 2 to 3 hours at a time, and have 5-6 sleeps in each 24 hour period. With a wakeful period that lasts about an hour between sleeps, during which time you'll need to feed her, at this stage there are only small windows of time for her to play and for you to rest.
Between 6 and 12 weeks, you may start to see a pattern of sleeping and feeding emerging and this will be your first glimpse of a routine. Sleeping patterns will change often in the first six months but it is only in the first few short weeks of life that your baby will really have no discernable routine at all.
Find tips on settling your baby to sleep.
Almost universally, babies sleep well on their stomachs. It's no coincidence that we, as babies, were all put in our cribs on our tummies, but as research has irrefutably shown sleeping your baby on her stomach is the single greatest risk factor of SIDS, therefore this is no longer an option.
Your baby should always be put to sleep on her back - don't be tempted to put her on her side as she may roll forward - with her feet near the bottom of her crib or cot. Her sleeping space should be well ventilated, unencumbered by soft toys or cot bumpers, and her bed clothes shouldn't be bulky.
