Becasue mine do and it's starting to drive me to distraction a bit
For example we have just been out with the puppy. We were walking through a field, along a dirt track. I had the lead with a very boisterous puppy on it, DS1 was trying to hold my hand and failing, so was clamped onto my arm, DS2 was holding my other hand, but whenever I tried to move either arm for any reason(such as blowing my nose) they still held onto my arm. I stop and they stop, I bent down to tie my shoelace and they were both almost on top of me, pawing at me, and arguing becasue we were on a little dirt track, which is only just wide enough for one person and we were all trying to fit along it.
Same if DH is with us, he has the puppy, and the 2 of them insist on holding/pawing at me, and if I try to chat to DH , they apeear either side of me, and I feel I can't chat. Then Ds2 wants me to "Play the alphabet game" so over and over we play guess 10 things beginning with A, B etc.
They are 10 and 8 now.
TBH I'm not sure why it irritates me so much, or why they do it. DH thinks it stem back to my mother who is very suffocating and overwhelming in her affection.
I do love my children dearly, but this is really winding me up, I keep saying "why don't you go and look for beasties ont eh plants", or "go and look for shells" if we ar eon teh beach, but no, they cling to me. DS1 though is far far worse than DS2, who will occasionally wander off to look at things
I feel better for getting that off my chest here, rather than say something to them which might upset them.
