"Just relax"

Yes, right - the words I heard so often during TTC are back. I now have a baby, everything went fine the first two months, he was a model baby, slept great, ate well, grew well. Then he hit a growth spurt and ever since his sleeping has been worse and I started to stress. Then at the 4-month checkup my pediatrician said he hadn't gained enough weight, so I started to stress more. She talked about spacing out nursing / complement with a bottle. I asked around, got advice which basically said the doctor was nuts, so I kept things the way they were. Went back to the pediatrician today, no change, just me completely stressed out (because baby's demand for feedings increased too and his sleeping got worse) and almost in tears.

So... she told me I'm too stressed, I worry about things that are not important, therefore I can't take position, just ask around for advice, and don't get any further. She's so right, I don't know what to do, I don't want to be stressed, I want to enjoy my baby, but I'm turning around in circles. Oh man, why do I make it myself so difficult? Why can't I decide if I'm just going to continue breastfeeding, if I'm going to add a bottle now and then, or if I'm going to start with solids (even though my baby is hardly 4.5 months old - the doc recommends it because I didn't want to complement with a bottle, but now that I'm home I wonder if that wouldn't be better after all - maybe his current 'growth spurt' isn't a growth spurt (because he didn't grow) but just a sign that he's hungry all the time because my milk doesn't give him all he needs?) - I know I am the only one who can change this, but how?

I'm going to see another doc tomorrow (to add to the stress), who's specialized in breast feeding. See what she has to say - and then I have to make a decision based on what my pediatrician said and what she says (at least I hope she doesn't think "growth spurts" are nonesense, as my pedi seems to think).

The doc gave me the name of a psychoanalyst, in case I want to talk to someone. Jeez, I'm pathetic, but it's probably a good idea (if someone can babysit?)...

Oh, btw, my baby is adorable and I love him very very much.
