Eulalia at a few days past his 6m "birthday" I started him on a couple of spoons (well maybe six) of pureed carrots and he was on three meals a day by the end of the first week.
I never took him to get weighed prior to this at all.
I give him all the usual stuff - pureed carrots, corn, peas, potatoes, rice, bananas,apples, porridge, yoghurt, etc. I have no idea if these are strictly recommended by the experts as first foods but I just use my common sense.
I use one of those Moule legume thingies to squish up the food so he can have "normal" rice , porridge etc and not "baby" ones, partly cause I have those in the house and partly because I am too mean to buy special baby foods and think they are a bit of a con.
He has had a few jars of stuff too and has only once refused - Organix pork and Veg casserole! I tasted it myself and it was pretty horrid.
The only reason I am not big on jars is because they taste very watered down to me, and how come they are so orange??!
I am currently housebound following my foot op. so sitting at the kitchen table chopping vegetables is no hardship at the moment.
Yes I do try to vary it a little bit and he can manage a degree of "lumpiness" in his food.
He has had no trouble at all accepting food from a spoon . ( my midwife told me today some HVs claim if you wait till 6m to introduce solids babies may struggle to eat from a spoon - she also said this is complete nonsense)
He still gets lots of breastmilk and his sleeping pattern has not altered at all (sadly)
I must say I am thoroughly enjoying watching him eat his litle dinners.
Good luck with your daughter.
