Our LO started solids (and by that, I mean about 5-6 tiny spoonfuls of very very watery rice cereal about 1 hour after her first am feed) at 5.5 months.
Before that, she was an awesome sleeper. Went down at 7pm, fed (EBM) at 11pm (sometimes) woke 1x at around 3am to feed again, and went back to sleep until 7 or 8am. She was quick and efficient about it, too!
Now, however, she wakes at around 9pm, feeds for 30 mins, wakes again at 11, feeds for another 30 mins, wakes again at 2 or 3 and again at around 5 am -- always taking forever to eat. This has been happening since the day we introduced solids. She is almost 6 months now.
For 2 days, I stopped the cereal, and it was a bit better (ie, she didn't wake up at 9pm to eat), but it was still a restless night.
THink it could be linked to the cereal? I should also mention that she has suddenly lost all interest in rolling.
