Hi.
I went from being a sole charge nanny to shared care when my boss went on maternity leave with number 2; this was my first position with a new born.
First few days - I tried to ensure she could sleep as much as possible, so if the baby was fed, I would then take the baby out for a walk, play with the children downstairs. I also made sure that she ate nutritious meals - so would make a bigger meal for the eldest so that MB could have a filling lunch instead of snacking or having a bowl of cereal etc. Also when feeding - I would bring her tea/drinks/snacks as she would be stuck on the couch for long periods. I found a sling was great as I got to attach the baby to me and still deal with the kids.
First few weeks - we tried to keep the older child in their routine; groups etc however with the summer holidays approaching this was often tricky - however we kept the routine of going out in the morning, and coming home for lunch and naps - then we would see Mummy and sometimes do things together - park, zoo, woodland walk etc - depending on how MB was feeling.
If Mb is around I try to let her have fun with the children, instead of trying to rush the kids out the door - depends on what mb's plans are - so they can have fun together. I know she likes doing bed time so I try to make sure that she gets that part of the day - even if it means having a crying baby downstairs with me - until she can come and deal with the baby.
I tried to be flexible with timings - so if everything is okay at home time I will leave, but if the baby is crying or the older child needs something then I will stay on - however as the months have gone on we have a routine in place so that doesn't always happen.
My boss is starting back at work now - so some days she's around and wants to enjoy time with the kids, some days she has so much to do - so will pop into the office or go out to do some work - I always try and make sure that we can try and meet up for feedings or just to say Hi. The baby is now taking a bottle so it's easier for us to do longer days - instead of having panicked calls asking where she is so we can find her for a feed.
If MB is at work - full day - then as before I will send texts telling her what we're upto or photos etc as i know she misses them both,
