Hi Grey86,
I'm not surprised that many new Mums don't get round to creating a mum-network; unless you're a natural social butterfly meeting new people is daunting, particularly when you are trying to adjust to having a baby.
I suffer from social anxiety; I was bullied all through school and can find communication difficult. I was determined that my little girl would not go through that, so I made networking my top priority. I figured if I found lots of friends for her to grow up with she'd never be lonely.
I joined NCT, but it can be hit and miss. I was in a group of 8 couples, we were all spread across the county. Whereas my friend from the same town was in a smaller group all living close together and they formed a close bond. It just caused me more anxiety worrying that they didn't like me and I regret the time spent breastfeeding one-handed as I tried to think of something meaningful to respond to whatever mini-crisis someone on the what's app group was having that day. The mums' what's app groups are ridiculous - on Mat leave I could get 50 messages a day, which just caused me stress.
Then it became hard to meet up even with the local mums as we all had conflicting nap times and feeding times. Once we went back to work we all had different days off.
So it's not all its cracked up to be.
My little girl is now nearly 3. She's made her own friends at nursery, and she now does the networking for me! The mum I see most is her best friend from nursery, who also ended up in her swimming class. My husband takes her swimming at the weekend so the parents met him first.
So if you're still looking to meet other mums (and dads!) there's lots of toddler classes like swimming, baby ballet, football etc - even if you work FT there's loads on at the weekend. A cheaper option is playgroups. Anywhere parents take their kids. You may recognise someone from nursery at a class or the park - or it may be your little one who recognises their friend! Once they're at school / pre-school they will tell you who their friends are and ask you to invite them to your house - mine does!
Even if you don't do the pick ups/ drop offs is your partner someone who can help break the ice? Any existing friends, neighbours or work colleagues with small children?
All my daughter's friends are in the next school year so they'll be moving on and my little girl will have to start from scratch, as will I. But I trust her to make new friends for us both.
