My baby is 18 weeks until recently I had been rocking her to sleep at night and then putting her in bassinet and allowing her to contact nap though out the day as she got longer sleep and would wake in cot during the day, she's recently started to get annoyed & over stimulated by the rocking to sleep so I thought I would start to encourage self soothing at night time she does it with some help light patting and putting her dummy back in but day naps are a no for self soothing sometimes she will self soothe for first nap but only sleeps 30 mins the rest of the day is basically a nightmare of me trying to get her to nap alone her getting frustrated and over tried and me giving in and contact napping with her which I'm worried isn't a good habit and I'm not being consistent, help
