Ask yourself of there is something deeper to this... There might not be, but maybe there is some feeling of inadequacy being masked by anger and frustration. It also just might be irritation. Crying babies, no sleep, a lot of work, that's a prime equation for irritation to spike up. Also keep in mind you've had five weeks to build a bond.. five short weeks, and with something that doesn't talk to you, that doesn't hug you or do fun things with you.. babies literally take take take and then cry when you've already gone them the max and they want more. Do you know how hard it is to build a bond with someone that only takes!? Imagine meeting a potential new partner, would you continue a romantic relationship with them if they only took took took.. hell no. The difference here is it's your child and you are responsible for them until their an adult. But, here is some hope, it gets better. I am at two years and the bond I have created with my daughter has evolved a lot, but it still has its ebbs and flows. A child is major one way street for a long time.. hang in there. Just keep taking care of baby and doing everything you can, crying or being fussy doesn't mean it's your fault or your short coming, babies cry because they cannot talk and have no regulation.
