Windy since I started weaning

[frans]

My DD is 5.5 months and I've just started to wean her as she's obviously ready for it (watching and trying to grab food, starting to wake up int he night again hungry etc). She's had baby rice for two days, then had pear yesterday. She's eating well - although I'm limiting her to 1 1/2 teaspoons each day at the moment - but she's started to get wind in the night and wake up crying at 4am, which she hasn't done for months. Last night was particularly bad. Is this linked to the food? And if so, is it a normal reaction and likely to improve? Many thanks
