ds1 is 3 years old & goes to nursery 2 days a week. He always talks about his friend Alex & the other week at a kiddies party I met Alex's mum. She seemed nice & we spoke about how much the boys seem to like each other. would it be unreasonable to bite the bullet & pop a note in alex's bag with my phone number on it, asking if he wants to come over one day to play? I hardly know the mum so it feels a bit weird & forward iykwim!
