DD3 is 6mo and up until now has always napped in her buggy downstairs (tiny open plan house). Recently she's started taking an age to settle and will refuse to sleep and increasingly needing to go into a sling to sleep.
I cannot continue with this - I have sciatica and tendonitis and having her in a sling is excruciating. As of next week I'll also be babysitting a friends young DC for a few hours a week and need to be more available too. I'll also need the space back downstairs so the buggy needs to go.
I want to get DD3 napping in her cot in her room. Currently she's in a crib for night time in our room but that will change. The issue I have is that I also have 2yo DD2 at home with me. How do I sleep train/get DD3 to sleep in a cot when I have a toddler roaming the house. She'll be 3 in a couple of months but she's still little. Toddler is no longer in a cot and there is about a 1% chance that I'd get her sat in her bed reading books while I'm doing nap time.
I need a strategy but I'm struggling. Does anyone have any ideas?
