Hey!!!
I am an American mom
I've lived here for about 6 years and have a 15-month old girl. I totally understand what you are feeling as I was going through the same. The first 4 months are the toughest and then it does get easier
I live in Feltham at the border of Hampton/ Richmond (where the big Sainsburys is). My dentist is in Teddington and a dear friend also lives there. I've actually been to a few baby clinics there, have you? Let me know if you would like to meet up
