On other facebook groups, like Brand New Moms, Tel Aviv mom's Support.
With my first child I loved to go to Gymboree and after paying for one class with your baby, you get to come and hang out in the facility during there open hours during the week. this was a great outing for my baby and myself and helping open me up to new friends.
My second child and first here in Israel, made her hangout the mall. There were so many new moms on maternity leave to have coffee with and walk around in the winter months.
With my third we spent a lot of time at the local pool watching the older ones. Here I had to make an effort to get to know the other mom's but it was always worth it in the end.
It is hard to put oursleves out there and build a supportive group of women around us, but there is nothing that will sustain you like your #girlsquad if you invest in it.
