Hiya. my DD is 17months old now. I went back to work 30 hours a week in January but I work shifts. 7-5pm days few days off, 5-3am lates few days off then 10pm-7am night shifts, 5 days off. My daughter is extremely clingy, tantrum prone and had never been left with anyone but her dad before i went back to work. I was worried.
My DD was 12months old and Breast feeding 9 TIMES A DAY!!! and EVERY HOUR through the night co sleeping and never spent a night in a cot in her life when I returned to work and i made no preparation at all apart from worry myself sick about how we would all cope.
I wish I hadn't worried so much. It was harder for me than it was for her. These babies are much more adaptable than we give them credit for. I left her with my parents or her dad and was allowed to come back to feed her when i had chance or could express at work but I threw it. She wouldn't take it from a bottle anyway.
It did us both a favour. Naturally and gradually the day feeds reduced and because I wasn't there at night, DD just had to get used to daddy re settling her in her cot without boob. She didn't put him through the same trauma because he hasn't got milk and she knew I wasn't coming. Her sleep has improved a lot. I still night feed when i bring her to bed after 3am when I am home.
coping with the house, well, have a bake day, freeze little tubs for baby to have handy for child carers. plenty of fruit to snack on etc. Get a slow cooker and prepare dinner in the morning on days off or before you go to work. do house work between you in dribs and drabs, just keep on top of it so you dont have a big clean up.
Naps - !! mine would only have her nap in the pram or the car - my parents and partner just take her in the pram/car when she is due because i STILL feed her to sleep for her nap and we both sleep together in the day when I am off (bliss). As someone said above, they realise that the carers havent got your boob milk and will go to sleep for them in other ways. DONT worry about their naps, if they are tired, they WILL sleep. (might not be for as long as when you are there but they get used to it).
Try not to worry too much, it all fits into place in the end. If only i had known this before I made myself ill with worry about returning to work and carrying on the breast feeding etc. You cope, you adapt and you will be surprised and in awe of your little one coping without you.
