when my son was born he was the same way.
he would cry non stop. and i ended up bringing him to emergency because i thought he was crying from constipation or something.
when we got there we told the nurse what was wrong, and she suggested a lactose free formula. we use Emfamil Lactose Free A .
The second we switched formulas my boyfriend and i noticed a difference.
we also gave him gripe water, a little in a nipple so he could get it all-only like half a tea spoon. but i even noticed it was not doing that much, he liked the taste of it only and cried more when it was gone.
we gave him something else called...Coil, and the same thing, he liked the taste.
he still cried alot, but not as much as before, it was at least bearable.
the formula you are using might be too strong for his tummy which might be giving him pain.
and if none of that works, i know its hard but you just have to bear with it.
my son cried alot till he was about 3 months old, it was tough and stressful, but my sister inlaw and mother inlaw and my mom helped me alot and so did my boyfriend.
if you have a few people who are supportive and can help you through this, its the best thing. that way your not over tired, frustrated and drained of all energy.
i know its tough, but it will get better.
also when my son was born i had a few nurses who called to see how things were going and asked if i had any questions, and they had told me that putting a baby in a car seat then putting him on the dryer is supposed to mimic the motion of a car ride and helps put them to sleep, i never tried it though, maybe i should have, also a vaccum, the sound helps them sleep. its actually quite loud in the womb and that sound of the vaccum might mimic what they were hearing and comfort them.
it was tough to get through, but the support i had was a huge help. you could call a nurse hotline too if you wanted to see what they can suggest for you too, but thats all i can remember right now.
my sons 5 months, and is completely different from how he was when he was first brought home. our whole family always compliments on what a good boy he is, how hes so quite and i giggle when i think back to when he was first born! he now only cries when hes hungry or tired.
hope that was helpful, hang in there hun!
