What is the longest it has taken for a child to adjust?

[Crayola kiddies]

I am a bit different .... I don't carry the daycare kids ... At all.... The two youngest that I have are 30 lbs each at 12 and 16 months respectively.... I would have serious back problems if I carried these kids around.... I sit on the floor and they can sit on my lap or beside me but they have to learn to play by them selves and carrying a child around doesn't promote that .... The last child I transitioned in nov shrieked as soon as I took my eyes off him.... I could be standing in front of him but if I looked at another child he lost his noodle.... Well too bad .... He was not going to get all the attention as I had 4 other kids. It lasted about 2 weeks and all of a sudden it was like a switch went off and now he's perfectly happy. This child came to me at 10.5 months and could only sit ( if you put him in a sitting position) and stand (again if you stood him next to something).... He could not crawl or roll over...so I put him in the middle of the room and put toys close but out if reach and if he wanted them he had to go get them. ...... He now speed crawls..... He can roll over and just this past week he mastered going from a standing position down to crawling because up till now if he pulled him self up at the couch or the play kitchen or some other toy he stood there till you helped him down .... So i worked hard at showing him how to do it himself ..... But if I was carrying him around all the time he wouldn't have mastered half of this stuff..... You have to put them on the floor and let them figure it out and be in control of their own happiness .... The sooner you leave them be and tune them out the sooner they stop .... Coddling doesn't help
