Canella sorry for mixing names up, blame fuzzy baby brain!
Later I never had a problem putting DS1 into a wrap except for the ends trailing on the wet floor, if you take baby out somewhere where you can't put them down there is the option of slipping baby out without untying the sling, or only partially untying it, but I don't actually recall taking him out anywhere I had no option of anywhere to put him down or anyone to hold him, at least not often...
The sling I have now is like a square of thick material withpadded straps coming from the top 2 corners - this is no prob to put on without putting baby down - you lean back slightly with baby on your chest, put the material over baby and straps over your shoulders, hold baby and sling with one hand and arm while bringing the straps around, under baby'S bottom and legs, swap arms, do the other, then tie - sounds odd maybe but it is easy - I was lucky that the friend who gave it to me showed me how the first time. I use the sling every time I go shopping somewhere without baby trollies (I am sure all supermarkets have them, and 2 child trollies, in the UK - here I always had to use sling in supermarkets with DS1 or let DD, who was only just 2, walk).
DD is better - she only has 5 days left at KiGa ever now! She could also write a bit at 3 but hasn't progressed loads - she can read simple Oxford Reading Tree books and loves to write (phonetic spelling mostly) but I have very deliberately stuck to English only and said she will learn German at school - partly due to my German not being good enough, partly due to the bored at school argument. She will be the very youngest child in her school year so I think a little head start from having a basic level of literacy in English will do no harm.
DS1 who is nearly 4 was totally uninterested in reading and writing til recently, though he has been able to pick his and his sisters names out from lists of names for ages, but suddenly the other day he started writing/ scratching letters and numbers on the ground with a stone and telling me what they were (correctly) so I guess they all learn in different ways and at their own pace!
Certainly once the non reading kids start school here they seem to get "up to speed" much faster than the average UK child who starts at 4, so I think waiting if they are not interested does no harm.
