Hi
No, you're not on your own, i felt awful when my DP was due to go back to work, i worried i would feel overwhelmed..and i only had DS2 as my other kids are 11 and 14 lol
Being a new mum can be very isolating, not least because you feel tied to the baby, tied to the house, BF is difficult at the best of times but mix that with the thought of BF while out, and if you haven't got a lot of nerve, it seems best just to stay in the house all day.
DS2 is now 8 weeks old and that feeling never really goes away but in fact is natures way of making sure you 'concentrate' on nothing else but baby..it wears off a little eventually.. Do you have people in RL who will support you, or who you can go visit so you have an excuse to get out?
I for instance made sure there was very little food in the house so i HAD to go out shopping.. something from when i had my DD and didn't leave the house for 2 months one time, she was only a few weeks old, i believe that was partly not knowing anyone, not having friends to visit, being a lone parent, and a little bit of PND in the mix.
I only left the house when i needed to get nappies and formula, get her weighed, and have her first set of injections, i had stocked up on enough things so i didn't have to leave the house, no WAY i was making that mistake again.
You can post and make friends on here, but IMO there is no substitute for getting out in the fresh air and having a walk.. it would help tire your DS1 out too
