i am not sure of professional services (though you should ask your pediatrician), but a form of the Ferber method sounds like its in order. first, the less a baby sleeps, the less a baby sleeps. and goes in reverse: the more a baby sleeps the more a baby sleeps. your little one is not getting enough sleep to feel calm enough to be put down.
before reading any further, you should note if there any changes in your life/family life/household that might be effecting your child. if that is so, then there might not be a quick answer solely having to do with your child. is she healthy after her wellness checks? is she ill?
if not, and you are too busy/tired to read the Ferber book ( though totally worth the read) is take some tips from it or the tips given in an excellent book called Baby 411 that is quick and easy to read and often in q&a form.
the first tip is to begin a schedule for your baby in the evening that might include: storytime, bath, feeding, bed. make sure it happens at roughly the same time every night. then, put your child down for the evening. say goodnight to her and leave the room. wait 3 minutes before entering the room again, though she will protest. this is going to begin the relearning process of self soothing, which according to doctors, children are unable to do on their own before 5 months. after 3 minutes of crying, enter the room again. soothe her by speaking in low tones, rubbing her leg or forehead. try not to pick her up.after 1 minute, say goodnight again and leave the room. now wait 5 min. before going in again. should she stop making noise before 5 minutes, super. should she protest, keep going in at 10 minute increments until she is asleep. this will be hard on you. no one likes to hear their child cry.
try this on a weekend. you will be tired.
after 4 to 6 days of this she should be ready to sleep on her own. she will still awaken. the important part about actually reading the book, is that it asks the tough questions: where does your child sleep? do you feed her everytime she awakens? if you feed her, you might want to try water instead of milk, and maybe she will feel it is less worth the waking. mostly she is waking to be soothed, and it sounds like she is waking after every sleep cycle is finished.
if all of this sounds like a mystery, i can't recommend Baby 411 more. i am a mother of an 8 month old, with a business i run that is taxing, and a husband with a similar kind of job. we have found time to read baby 411 to eachother over a.m. tea. good luck and hope you get more zzzzzzzzzzz's.
