AIBU to choose a different childminder - I have not handed over the contract that she gave me to sign.
About a month ago me and my DH went to visit a childminder at her home to see if she would be suitable for our DD. First of all DD took to her straight away (she was 5 month at the time). The childminder seemed really nice, down to earth and does anything to help parents out.
Here's my reasons for making me want to reconsider; her back garden has been ruined by her dog, she has a driveway which she says she lets the children play on and she supervises them - she's lives on a housing estate. However she said that she takes the children to the park often so they can play. I asked her where my child could nap, she said she lets them nap on the couch with cushions on the floor; she said she's never had any child fall from the couch. She is a smoker but said she does not smoke around the children, she said she just wouldn't do it and it is also illegal. (When she came round my house to bring me the contract the paper, in my opinion smelt like smoke) her house didn't smell of smoke, so maybe she had a cigarette after she finished childminding but before she came to my house?? She was honest about her OFSTED report, she said she got a 'needs improvement' as she could not find some paperwork but she is adamant she has that paperwork somewhere in the house. There was one child (13 yo I think)who she childminds at the house waiting to get picked up when we were there discussing things with the childminder. When the child's parents arrived (waited in the car) the child ran straight out of the house without saying bye to the childminder. Was this because she was shy around me and DH or does she dislike the childminder?? The childminders daughter was there, she seemed very nice also.
Good points are the childminder offered to bring our DD back home at 6pm each time she childminds as DH drives a van for work and can not have a car seat in the van. She said she would provide nappies, wipes etc - we would not expect her to do so, we would take our own. She would charge us £60pw this includes meals and snacks - that's the cheapest by far, however money is not a issue when it comes to my DD's well-being. She was the only childminder we found who started early enough for us, I start work at 7ma so need childcare from 6:30am, not many childminders work that early. The childminder does seem like a nice person and easy to get along with. She said she would send me photos of my DD on WhatsApp. The 13yo who she childminds has apparently been childminded since she was 6 months old by this childminder. She gave me reviews to read I read through them, they were good - I'm being paranoid about them thinking that she got somebody to write them for her. I don't know why 
AIBU to be abit weary or am I just looking into little things too much? She is kind of our only option for childcare as there are no nursery's that are open at 6:30am & family can not help with childcare. I am feeling nervous and uneasy and need your honest opinions. I will not put my DD in danger I'm just not sure if I'm being too paranoid. I've never had to deal with childminders before as DD is our first child.
