hate to say it mom but this is par for the course. this is normal. babies dont get into a rhythm or schedule. they are hungry when they are hungry, wet when wet, tired when tired (which until around 3 months old is all the time)
just keep plugging away. never make an infant cry it out, unless you are at your wits end and afraid of hurting baby. if someone else is there to take baby for you, do it and take a walk. but habitual crying it out breaks down trust, so steer clear of that..
just do what you can. babies grow a lot in the first year nad they need to eat a lot. they also only have tummies the size of their fist, so it fills and empties fast! its great that your hubby will give a bottle at night and though im a strong breastfeeding supporter, if you get better rest when hubby does one bottle for formula, thats great!
contact a local or nearby la leche league. they will give you the mom support you desperatly need! :D also it might give you a break to just talk to other moms and get out of the house you know?
good luck.
one place i REALLY trust (besides la leche league) is www.askdrsears.com.
awesome info on there! :D
sleep might never be the same, but life is so much more wonderful with a baby in it.
if you feel afraid of hurting your baby, if you feel angry or upset all the time, dont hesitate to seek the help of your doctor. postpartum depression is common and you can only get help if you ask for it. :D
good luck, and simply follow your instincts! :D
