That must be so difficult! I guess kids are more happy to meet new people as a transient friend, they're used to teaching assistants and teachers coming and going, childminders, etc.. so long as it's not too much of a strong emotional bond formed between child and partner that doesn't end up working- the risk being choosing a partner for their relationship with your child as opposed to with you! Short answer: I think adults are more bothered than kids are about it...
