We do bath time together if DD2 (6 mo) can last long enough for me to dress DD1 (2.8yrs) after, then DD1 watches something on iPad in her room while I feed DD2 in the other room. iPad saves me at bedtime, not sure how I would be coping alone every night otherwise!!
Difficult if DC2 will be unhappy even if with you while you settle DC1.
We bath together and get both into pjs, then read story to toddler and baby in toddlers room. Sometimes feed baby during story if he can't wait. Then night night toddler and then feed baby and settle to cot in his room.
DS2 (4mo) has basically cried himself to sleep tonight due to me not being able to concentrate on him while I put DS1 (2.8) to bed . He cries and cries if I have him in ds1s bedroom while I do bedtime, he upsets ds1 too. He won't settle yet on his own though. So I'm going between two rooms trying to deal with them nboth but there are an inevitable few minutes when I just have to finish ds1 and in those few minutes tonight ds2 crashed in tears.
How the hell do I negotiate this minefield on the nights I'm on my own with them?
