This isn't really a direct reply to the original question about increasing dosage of celexa, but since I found it while doing my own research re: my current pregnancy I thought I'd share my own experience as a *possible* warning about baby's sleep to others breastfeeding while taking celexa. I breastfed my first son for 13 months on a 20-30 mg dosage of celexa, and thought I had no problems at all--he developed normally and is very bright. It was only long after I had weaned him that I stumbled across some surprising information about celexa. I had always been told to take the celexa in the morning and had for years without thinking about it--apparently this is because about 85% of people who take it have a bit of a stimulant effect from it. Personally, I had such low energy levels that I even frequently had to come home at lunchtime for a nap before ever getting pregnant, so it never dawned on me that celexa could act as a stimulant.
Now I wonder whether my son's horrible sleep problems his first year can be attributed in part to the celexa in the breastmilk. He was difficult to get to sleep, and slept for short periods (for the first 8 months I don't think he ever napped longer than 20 minutes unless he was being rocked or pushed in the stroller, and woke about every 1 1/2 hours at night). Although I nursed on demand until 13 months when I was with him, I had gone back to work part time and he was getting formula as well. Looking back, I think his sleep improved as the proportion of formula increased, and his sleep improved dramatically once he was weaned completely. I know that breastfed babies in general have shorter, lighter sleep cycles, and I know that once the comfort of nursing was no longer available in the middle of the night his incentive to call for me was lessened, but I can't help wondering if part of the problem was that my breastmilk was actually stimulating him and making long, deep periods of sleep more difficult.
I'm 7 months pregnant with #2 and taking 30 mg of celexa, and plan to breastfeed again. But this time I've been reading up on all the techniques for encouraging good sleep, and if this baby is having as many sleep problems as his brother, I'll be experimenting to see if there is a correlation between the celexa and his sleep.
Has anyone else noticed a possible correlation with their babies?
