DunnyJo my DS is the same age, I am also a SAHM.
I am just settling into a routine in a new area (we moved in August), so I don;t know anyone either.
8am - get up, get breakfast
8.30 - Shower, get dressed, get DS dressed, tidy house, put laundry on etc
9.30 - usually go out somewhere in the mornings. One morning DS goes to Tumbletots. The rest we go shopping in town, visit the garden centre (pets, fish, have a coffee), go to soft play, to the park if it's nice, etc. One morning do housework.
12 - lunch
1.30 pm - DS has a nap, I come on MN, or do other things online, etc
3 pm - get DS up, sometimes we go out again, walk to the shops, or supermarket shopping, otherwise get something specific out for him to do e.g. playdough, drawing, etc
5 pm - get DS tea, wash up, clear up toys etc
6.30 pm - DH gets home from work, baths DS
7 pm - DS in bed
After Christmas am hoping to find another activity for DS e.g. music group. The groups can be expensive but I think DS needs to be mixing with other children a bit.
I don;t like those free for all mum & toddler groups much either.
I find I have to plan something specific for each day otherwise I would sit in PJ's all day and go mad.
