I am a first time mum to a boy, who will be 2 in December.
We moved to a new area before he was born so I don't know any other mums apart from the odd chat at toddler groups and none of my friends/family have children or children of a similar age. I read a lot about developmental stages etc and try to make sure he has the right support and encouragement from my husband and I but nothing quite like real life experience from other parents!
He is big, over 90th percentile for height and weight. When I see other children at the park, a lot of them of his size seem much more developed. Some, I can tell are older, but smaller, but others seem to be able to climb/jump much more confidently than my son. I don't know if I am being cautious in what I let him do just yet but I want to help him spread his wings, but safely!
For example, I watched a mum climb some very high small metal steps with her son who was about the same size as mine and he then went down the very high slide while she climbed down (he seemed a bit unsure but smiled as he got going) I wouldn't do that with mine yet but maybe I should?
If you could share your wisdom about 21 months olds it would be much appreciated!
